Resumen
The paradigmatic spin-boson model considers a spin degree of freedom interacting with an environment typically constituted by a continuum of bosonic modes. This ubiquitous model is of relevance in a number of physical systems where, in general, one has neither control over the bosonic modes, nor the ability to tune distinct interaction mechanisms. Despite this apparent lack of control, we present a suitable transformation that approximately maps the spin-boson dynamics into that of a tunable multiphoton Jaynes-Cummings model undergoing dissipation. Interestingly, the latter model describes the coherent interaction between a spin and a single bosonic mode via the simultaneous exchange of n bosons per spin excitation. Resorting to the so-called reaction coordinate method, we identify a relevant collective bosonic mode in the environment, which is then used to generate multiphoton interactions following the proposed theoretical framework. Moreover, we show that spin-boson models featuring structured environments can lead to non-Markovian multiphoton Jaynes-Cummings dynamics. We discuss the validity of the proposed method depending on the parameters and analyse its performance, which is supported by numerical simulations. In this manner, the spin-boson model serves as a good analogue quantum simulator for the inspection and realization of multiphoton Jaynes-Cummings models, as well as the interplay of non-Markovian effects and, thus, as a simulator of light-matter systems with tunable interaction mechanisms.

Resumen
We proposed a modified Schwinger boson theory for quantum Heisenberg model which naturally satisfies the spin identity [Formula: see text], and in which the redundant degrees of freedom due to an average treatment of the constraints are discarded by introducing new boson operators. The results, either for free energy or for spin-spin correlation are exactly the same as those of Takahashi’s modified spin wave theory.7 This theory provides a unified approach to study the ferromagnet and antiferromagnet on equal footing. As such it would be a good starting point for discussing antiferromagnetism in the presence of holes, where ferromagnetic component plays an important role.

Resumen
We study the spin-boson model with a particle number cutoff. The spin-boson model is a simplified model of an atom interacting with a quantized photon field. An important physical phenomenon that one would like to understand rigorously on this model is the phenomenon of radiative decay, where the atom asymptotically relaxes to its ground state by emitting photons. One of the possible approaches to radiative decay is through scattering theory. For the cutoff spin-boson hamiltonian, we prove the existence and asymptotic completeness of the channel wave operators, which have natural interpretation in terms of the radiative decay property.

The semiclassical approximation to the spin-boson model leads to interesting nonlinear effects, triggered by the important action of the reaction field, namely the influence that the boson "bath" exerts on the spin system.

Resumen
The region of the nuclear chart around A~100 is an area of structural changes where different shapes coexist and therefore, an interesting place to study structural evolution and test nuclear models. Within the clement that populate this region, zirconium is one which is expected to present well deformed states, but for which little experimental data has been measured so far. The structure of the 102-108Zr nuclei has been studied using the Interactiug Boson Model (IBM). Energy states and transition probabilities have been predicted and tested using the limited amount of existing experimental data. However, the results of these calculations produced several possibilities, so knowledge about non-yrast. states is needed in order to deepen the understanding of the structural changes in zirconium nuclei. Therefore a. series of experiments to measure non-yrast states of 102- 108Zr are required. A new technique, for separating different states of nuclei, has been developed and tested at the University of Jyvaskyla, using the IGISOL III facility for the known case of 100Nb β-decay into 100 Mo. This technique has been successfully extended to allow the separate study of the gamma.-ray decay of states populated by the different parent states. Lower spin states of 102- 108Zr are populated via beta-decay from 102- 108y' In order to measure the non-yrast states of 102- 108Zr post-trap online spectroscopy will be used at IGISOL IV. IGISOL IV is the improved version of IGISOL 111 and is currently under construction. Part of my Ph.D. consisted of helping with the development of IGISOL IV, the improvements of this facility are explained in this thesis alongside its operation and several tests performed during 2012.

Resumen
Le boson de Higgs dans le mode de désintégration WW* est observé avec un excès d'événements sur le bruit de fond de 6,1 écarts-types dans l'état final avec dilepton, alors que l’importance du signal attendu pour le boson de Higgs du modèle standard est de 5,8 écarts-types. Une indication pour la production du processus en fusion de bosons vecteurs (VBF) est également obtenue avec une importance de 3,2 écarts-types. Les résultats sont obtenus à partir d'un échantillon de données en collisions proton-proton enregistrées par le détecteur ATLAS au LHC, qui correspond à une luminosité intégrée de 4,5fb-1 à √s = 7 TeV et 20,3fb-1 à √s = 8 TeV. Tous les canaux de saveur leptonique (ee/μμ et eμ/μe)) sont analysés, y compris de différentes catégories en multiplicité de jets (nj = 0, 1,≥ 2). Les canaux ayant différentes saveurs leptoniques eμ/μe ont la meilleure sensibilité au signal. Les catégories à basse multiplicité de jet sont contribuées principalement par la production du processus en fusion de gluon-gluon (ggF), tandis que la catégorie à haute multiplicité est plus sensible à la production VBF. Les bruits de fond dans différents canaux et catégories varient et leurs contributions sont obtenues dans la plupart de cas à partir des données avec des régions de contrôle ou validation. Les bruits de fond dominants sont les productions WW et le quark top. Dans les canaux ayant la même saveur leptonique, la contribution Drell-Yan est aussi une autre source importante. Pour le boson de Higgs à 125,36GeV, le rapport du signal mesuré sur celui du modèle standard est de 1,09+0,16-0,15 (stat.) +0,17-0,14 (syst.). Les rapports correspondants pour les productions ggF et VBF sont de 1,02±0, 19 (stat.) +0,22-0,18 (syst.) et 1,27+0,44-0,40 (stat.) +0,30-0,21 (syst.), respectivement. La section efficace totale mesurée à √s = 8 TeV est de σ(gg → H → WW∗) =8TeV est de σ(gg → H → WW∗) et σ(VBFH → WW∗) = 0,51+0,17−0,15 (stat.)+0,13−0,08 (syst.) pb. La section efficace fiducielle est aussi mesurée pour la production ggF dans l'était final exclusif avec zéro ou un seul jet. En plus des couplages, d'autres propriétés du boson de Higgs, notamment le nombre quantique de spin et la largeur totale de désintégration, sont également étudiées en utilisant les données de 8TeV et les canaux ayant différentes saveurs leptoniques seulement. L'étude du spin est basée sur un échantillon de données dominé par les événements sous le pic de résonance en utilisant les catégories de jet nj ≤ 1. L'hypothèse sur le spin-parité JCP = 0++ du modèle standard est comparée à d'autres hypothèses. Les données sont compatibles avec le modèle standard et les limites sont placées sur des hypothèses alternatives de spin. Les événements dans la queue hors pic de résonance à haute masse dans la catégorie inclusive de jet sont ensuite utilisés pour mesurer les couplages du boson de Higgs hors de sa couche de masse et pour imposer une contrainte sur la limite supérieure de la largeur totale du boson de Higgs, lorsque certaines hypothèses sont faites
The Higgs boson decays to WW* is observed based on an excess of events over background of 6.1 standard deviations in the dilepton final state including all flavour channels (ee/μμ and eμ/μe) and jet multiplicity categories (nj = 0, 1,≥ 2), where theStandard Model expectation is 5.8 standard deviations. Evidence for thevector-boson fusion (VBF) production process is also obtained with a significance of3.2 standard deviations. The different favour channels eμ/μe have the best expected signal sensitivity. The low jet multiplicity categories are dominantly contributed by the gluon-gluon fusion (ggF) production process whereas the large jet multiplicity category has the best sensitivity to the VBF production process. The results are obtained from proton-proton collision data recorded by the ATLAS detector at the LHC, corresponding to 4.5fb-1 at √s = 7TeV and 20.3fb-1 at √s = 8TeV. The background contribution in each channel and jet multiplicity category varies and is determined mostly with data-driven techniques with dedicated control or validation regions. The dominant background processes are the continuum WW and top quark productions. In the same flavour channels (ee/μμ), the Drell-Yan process is another important background source. For a Higgs boson mass of 125.36GeV, the ratio of the measured value to the expected value of the total production cross section times branching ratio fraction is 1.09+0.16-0.15 (stat.) +0.17-0.14 (syst.). The corresponding ratios for the gluon fusion and vector-boson fusion production modes are 1.02 ± 0.19 (stat.)+0.22−0.18 (syst.) and 1.27+0.44-0.40 (stat.) +0.30-0.21 (syst.), respectively. At √s = 8TeV, the total production cross section is measured to beσ(gg → H → WW∗) = 4.6±0.9 (stat.)+0.8−0.7 (syst.) pb σ(VBFH → WW∗) = 0.51+0.17−0.15 (stat.)+0.13−0.08 (syst.) pb. The fiducial cross section is determined for the gluon-fusion process in exclusive final states with zero and one associated jet. In addition to the on-shell couplings, other properties of the Higgs boson, namely the spin quantum number and the total decay width, are also studied using the 8TeV data and the different flavour channels only. The spin study is based on the on-shell dominated event sample using the nj ≤ 1 jet categories. The Standard Model spin-parity JCP = 0++ hypothesis is compared with alternative hypotheses. The data are found to be consistent with the Standard Model and limits are placed on alternative spin hypotheses.The off-shell events in the high mass tail from the inclusive jet category are then used to measure the off-shell couplings and impose a constraint on the upper limit of the total width of the Higgs boson indirectly, when certain assumptions are made

Resumen
Au cours des dernières années, le domaine de l'interaction lumière-matière a fait un pas de plus en avant avec l'avènement des qubits supraconducteurs couplés ultra-fortement à des guides d'ondes ouverts. Dans ce contexte, un qubit devient simultanément couplé à de nombreux modes du guide d'onde, se transformant ainsi en un objet hybride lumière-matière hautement intriqué. L'étude de nouveaux phénomènes dynamiques qui émergent de la grande complexité de ces systèmes quantiques à N-corps est l'objectif principal de cette thèse.Dans une première étape cruciale, nous abordons l'évolution dans le temps d'un tel système en utilisant une nouvelle technique numérique basée sur un développement complet du vecteur d'état en termes d'états cohérents multimodes. Inspirée par des approches semi-classiques antérieures, cette technique numériquement exacte fournit un progrès important par rapport aux méthodes de pointe qui ont été utilisées jusqu'à présent pour étudier le régime de couplage ultra-fort à N-corps. Fondamentalement, cette approche préserve également le détail de la dynamique du système complet réunissant le guide d'onde et le qubit, permettant à la fois d'effectuer la tomographie et d'extraire la diffusion multi-particule des degrés de liberté du guide d'onde.Une exploration du régime de couplage ultra-fort multi-mode utilisant cette nouvelle technique a conduit aux deux prédictions théoriques fondamentales de cette thèse. La première démontre que le rayonnement émis spontanément par un qubit excité prend la forme d'un chat de Schrödinger de lumière, un résultat étonnamment différent de l'émission de photon unique habituelle en optique quantique. La seconde prédiction concerne la diffusion de signaux cohérents de faible puissance sur un qubit, un protocole expérimental très courant en laboratoire. De façon remarquable, il est montré que la non-linéarité du qubit, transférée au guide d'onde par l'interaction ultra-forte avec la lumière, est capable de diviser les photons du faisceau entrant en plusieurs photons de plus basse énergie, conduisant à l'émergence d'un continuum basse fréquence dans le spectre de puissance, qui domine le signal hors-résonant. En étudiant la fonction de corrélation de second ordre dans le champ rayonné, il est également démontré que l'émission en couplage ultra-fort présente des signatures caractéristiques de la production de particules.Dans la dernière partie de la thèse, la fonction de corrélation de second ordre est à nouveau étudiée, mais cette fois expérimentalement, et dans le régime du couplage modéré. Bien que les mesures soient encore préliminaires, cette partie de la thèse présente un compte-rendu instructif de la théorie de la mesure du signal et permet de comprendre en détail la procédure expérimentale impliquée dans la mesure des signaux quantiques. De plus, à l'avenir, les développements expérimentaux et les outils de simulation décrits pourraient être appliqués aux signaux émis par des qubits ultra-fortement couplés, afin d'observer les signatures de production de particules révélées par la fonction de corrélation du second ordre
In the recent years, the field of light-matter interaction has made a further stride forward with the advent of superconducting qubits ultra-strongly coupled to open waveguides. In this setting, the qubit becomes simultaneously coupled to many different modes of the waveguide, thus turning into a highly intricate light-matter object. Investigating the wealth of new dynamical phenomena that emerge from the high complexity of these engineered quantum many-body systems is the main objective of this thesis.As a first crucial step, we tackle the time-evolution of such a non-trivial system using a novel numerical technique based on an expansion of the full state vector in terms of multi-mode coherent states. Inspired by earlier semi-classical approaches, this numerically exact method provides an important advance compared to the state-of-the-art techniques that have been used so far to study the many-mode ultra-strong coupling regime. Crucially, it also keeps track of every detail of the dynamics of the complete qubit-waveguide system, allowing both to perform the tomography and to extract multi-particle scattering of the waveguide degrees of freedom.An exploration of the many-mode ultra-strong coupling regime using this new technique led to the two core theoretical predictions of this thesis. The first demonstrates that the radiation spontaneously emitted by an excited qubit takes the form of a Schrödinger cat state of light, a result strikingly different from the usual single-photon emission known from standard quantum optics. The second prediction concerns the scattering of low-power coherent signals on a qubit, a very common experimental protocol performed routinely in laboratories. Most remarkably, it is shown that the qubit non-linearity, transferred to the waveguide through the ultra-strong light-matter interaction, is able to split photons from the incoming beam into several lower-energy photons, leading to the emergence of a low-frequency continuum in the scattered power spectrum that dominates the inelastic signal. By studying the second-order correlation function of the radiated field, it is also shown that emission at ultra-strong coupling displays characteristic signatures of particle production.In the final part of the thesis, the second-order correlation function is investigated again, but this time experimentally, and in the regime of moderate coupling. Although the results are still preliminary, this part of the thesis will provide an instructive account of signal measurement theory and will allow to understanding in-depth the experimental procedure involved in measuring quantum microwave signals. Moreover, the experimental developments and microwave simulations tools described in this section could be applied in the future to signals emitted by ultra-strongly coupled qubits, in order to observe the signatures of particle production revealed by the second-order correlation function

Resumen
For more than 30 years the Standard Model has been the theoretical foundation for particle physics. The theory has been verified successfully by experimental tests. Its biggest shortcoming is the non-discovery of the Higgs boson,responsible for giving the other particles masses. Despite its success there are hints that the Standard Model is not the complete theory and many extensions of it, such as supersymmetry, have been proposed. Extended theories often predict the existence of a charged Higgs boson and its detection will be a clear sign of physics beyond the Standard Model. The main focus in this thesis is on various phenomenological aspects of the charged Higgs boson. For favorable mass and couplings direct detection is shown to be possible at the Large Hadron Collider in production with an associated W boson. It is also shown how a light charged Higgs can have measurable effects on spin correlations in decays of pair-produced top quarks. The charged Higgs boson can also be seen indirectly, in for example B-meson decays, which can be used to put constraints on its mass and fermion couplings. Exclusion limits in two supersymmetric models are given together with a comparison with the discovery potentials for the LHC experiments. A tool for calculating properties, such as masses and decays, of both charged and neutral Higgs bosons in the Two-Higgs-Doublet Model is also presented. B-meson decays can also be used to test aspects of the strong interaction. Part of this thesis deals with improving and applying phenomenological models to B-meson decays. Although these models are not derived from first principles, their success shows that they capture important features of non-perturbative strong interactions.

Resumen
Light-harvesting in nature is known to work differently than conventional man-made solar cells. Recent studies found electronic excitations, delocalised over several chromophores, and a soft, vibrating structural environment to be key schemes that might protect and direct energy transfer yielding increased harvest efficiencies even under adversary conditions. Unfortunately, testing realistic models of noise assisted transport at the quantum level is challenging due to the intractable size of the environmental wave function. I developed a powerful tree tensor network states (TTNS) method that finds an optimally compressed explicit representation of the combined electronic and vibrational quantum state. With TTNS it is possible to simulate exciton-phonon quantum dynamics from small molecules to larger complexes, modelled as an open quantum system with multiple bosonic environments. After benchmarking the method on the minimal spin-boson model by reproducing ground state properties and dynamics that have been reported using other methods, the vibrational quantum state is harnessed to investigate environmental dynamics and its correlation with the spin system. To enable simulations of realistic non-Born-Oppenheimer molecular quantum dynamics, a clustering algorithm and novel entanglement renormalisation tensors are employed to interface TTNS with ab initio density functional theory (DFT). A thereby generated model of a pentacene dimer containing 252 vibrational normal modes was simulated with TTNS reproducing exciton dynamics in agreement with experimental results. Based on the environmental state, the (potential) energy surfaces, underlying the observed singlet fission dynamics, were calculated yielding unprecedented insight into the super-exchange mediated avoided crossing mechanism that produces ultrafast and high yield singlet fission. This combination of DFT and TTNS is a step towards large scale material exploration that can accurately predict excited states properties and dynamics. Furthermore, application to biomolecular systems, such as photosynthetic complexes, may give valuable insights into novel environmental engineering principles for the design of artificial light-harvesting systems.

Resumen
This text provides a uniform and consistent approach to diversified problems encountered in the study of dynamical processes in condensed phase molecular systems. Given the broad interdisciplinary aspect of this subject, the book focuses on three themes: coverage of needed background material, in-depth introduction of methodologies, and analysis of several key applications. The uniform approach and common language used in all discussions help to develop general understanding and insight on condensed phases chemical dynamics. The applications discussed are among the most fundamental processes that underlie physical, chemical and biological phenomena in complex systems. The first part of the book starts with a general review of basic mathematical and physical methods (Chapter 1) and a few introductory chapters on quantum dynamics (Chapter 2), interaction of radiation and matter (Chapter 3) and basic properties of solids (chapter 4) and liquids (Chapter 5). In the second part the text embarks on a broad coverage of the main methodological approaches. The central role of classical and quantum time correlation functions is emphasized in Chapter 6. The presentation of dynamical phenomena in complex systems as stochastic processes is discussed in Chapters 7 and 8. The basic theory of quantum relaxation phenomena is developed in Chapter 9, and carried on in Chapter 10 which introduces the density operator, its quantum evolution in Liouville space, and the concept of reduced equation of motions. The methodological part concludes with a discussion of linear response theory in Chapter 11, and of the spin-boson model in chapter 12. The third part of the book applies the methodologies introduced earlier to several fundamental processes that underlie much of the dynamical behaviour of condensed phase molecular systems. Vibrational relaxation and vibrational energy transfer (Chapter 13), Barrier crossing and diffusion controlled reactions (Chapter 14), solvation dynamics (Chapter 15), electron transfer in bulk solvents (Chapter 16) and at electrodes/electrolyte and metal/molecule/metal junctions (Chapter 17), and several processes pertaining to molecular spectroscopy in condensed phases (Chapter 18) are the main subjects discussed in this part.

Resumen
In a generic quantum mechanical description of a molecule interacting with its thermal environment, the molecule is represented as a few level system (in the simplest description just two, for example, ground and excited states) and the environment is often modeled as a bath of harmonic oscillators. The resulting theoretical framework is known as the spin–boson model, a term that seems to have emerged in the Kondo problem literature (which deals with the behavior of magnetic impurities in metals) during the 1960s, but is now used in a much broader context. Indeed, it has become one of the central models of theoretical physics, with applications in physics, chemistry, and biology that range far beyond the subject of this book. Transitions between molecular electronic states coupled to nuclear vibrations, environmental phonons, and photon modes of the radiation field fall within this class of problems. The present chapter discusses this model and some of its mathematical implications. The reader may note that some of the subjects discussed in Chapter 9 are reiterated here in this more general framework. In Sections 2.2 and 2.9 we have discussed the dynamics of the two-level system and of the harmonic oscillator, respectively. These exactly soluble models are often used as prototypes of important classes of physical system. The harmonic oscillator is an exact model for a mode of the radiation field and provides good starting points for describing nuclear motions in molecules and in solid environments. It can also describe the short-time dynamics of liquid environments via the instantaneous normal mode approach. In fact, many linear response treatments in both classical and quantum dynamics lead to harmonic oscillator models: Linear response implies that forces responsible for the return of a system to equilibrium depend linearly on the deviation from equilibrium—a harmonic oscillator property! We will see a specific example of this phenomenology in our discussion of dielectric response in Section 16.9.
