Abstract:
This paper is concerned with the modeling and analysis of quantum dissipation and diffusion phenomena in the Schrödinger picture. We derive and investigate in detail the Schrödinger-type equations accounting for dissipation and diffusion effects. From a mathematical viewpoint, this equation allows one to achieve and analyze all aspects of the quantum dissipative systems, regarding the wave equation, Hamilton–Jacobi and continuity equations. This simplification requires the performance of “the Madelung decomposition” of “the wave function”, which is rigorously attained under the general Lagrangian justification for this modification of quantum mechanics. It is proved that most of the important equations of dissipative quantum physics, such as convection-diffusion, Fokker–Planck and quantum Boltzmann, have a common origin and can be unified in one equation.

Abstract:
We study the barrier penetrability in the frame of the Lindblad theory of open quantum systems. In addition to the diagonal elements of the density matrix, leading to the Gamow’s formula, new terms, describing energy dissipation and spectral line broadening effects are obtained. It is shown that the presence of a dissipative environment increase the barrier penetrability, in accordance with a very simple physical interpretation: for a system initially found in its ground state the dissipation can lead only to transitions to the reaction channels where lower-energy levels exist.

Abstract:
With the recent development of experimental technology, the ability to control the dissipation in quantum many-body system is greatly enhanced. Meanwhile, many new breakthroughs are achieved in detecting the quantum states and others. All these advances make it necessary to establish a new theory for calculating the dissipative dynamics in strongly correlated sstems. Very recently, we found that by taking the interactions between the system and the bath as a perturbation, a systematic dissipative response theory can be established. In this new approach, the calculation of dissipative dynamics for any physical observables and the entropies can be converted into the calculation of certain correlation functions in initial states. Then we discuss how Markovian approximation at low temperature limit and at high temperature limit can be reached Also, we review the progress of the dissipative dynamics in open Bose-Hubbard model. In the fourth section, we review recent progress of entropy dynamics of quench dynamics of an open quantum system. Finally, we draw a conclusion and discuss possible development in the future.

Abstract:
Starting from the geometric description of quantum systems, we propose a novel approach to time-independent dissipative quantum processes according to which energy is dissipated but the coherence of the states is preserved. Our proposal consists of extending the standard symplectic picture of quantum mechanics to a contact manifold and then obtaining dissipation by using appropriate contact Hamiltonian dynamics. We work out the case of finite-level systems for which it is shown, by means of the corresponding contact master equation, that the resulting dynamics constitute a viable alternative candidate for the description of this subclass of dissipative quantum systems. As a concrete application, motivated by recent experimental observations, we describe quantum decays in a 2-level system as coherent and continuous processes.

Abstract:
Ma thèse de doctorat était consacrée à l'étude des systèmes quantiques à plusieurs corps dissipatifs et pilotés. Ces systèmes représentent des plateformes naturelles pour explorer des questions fondamentales sur la matière dans des conditions de non-équilibre, tout en ayant un impact potentiel sur les technologies quantiques émergentes. Dans cette thèse, nous discutons d'une décomposition spectrale de fonctions de Green de systèmes ouverts markoviens, que nous appliquons à un modèle d'oscillateur quantique de van der Pol. Nous soulignons qu’une propriété de signe des fonctions spectrales des systèmes d’équilibre ne s’imposait pas dans le cas de systèmes ouverts, ce qui produisait une surprenante "densité d’états négative", avec des conséquences physiques directes. Nous étudions ensuite la transition de phase entre une phase normale et une phase superfluide dans un système prototype de bosons dissipatifs forcés sur un réseau. Cette transition est caractérisée par une criticité à fréquence finie correspondant à la rupture spontanée de l'invariance par translation dans le temps, qui n’a pas d’analogue dans des systèmes à l’équilibre. Nous discutons le diagramme de phase en champ moyen d'une phase isolante de Mott stabilisée par dissipation, potentiellement pertinente pour des expériences en cours. Nos résultats suggèrent qu'il existe un compromis entre la fidélité de la phase stationnaire à un isolant de Mott et la robustesse d'une telle phase à taux de saut fini. Enfin, nous présentons des développements concernant la théorie du champ moyen dynamique (DMFT) pour l’étude des systèmes à plusieurs corps dissipatifs et forcés. Nous introduisons DMFT dans le contexte des modèles dissipatifs et forcés et nous développons une méthode pour résoudre le problème auxiliaire d'une impureté couplée simultanément à un environnement markovien et à un environnement non-markovien. À titre de test, nous appliquons cette nouvelle méthode à un modèle simple d’impureté fermionique
My PhD was devoted to the study of driven-dissipative quantum many-body systems. These systems represent natural platforms to explore fundamental questions about matter under non-equilibrium conditions, having at the same time a potential impact on emerging quantum technologies. In this thesis, we discuss a spectral decomposition of single-particle Green functions of Markovian open systems, that we applied to a model of a quantum van der Pol oscillator. We point out that a sign property of spectral functions of equilibrium systems doesn't hold in the case of open systems, resulting in a surprising ``negative density of states", with direct physical consequences. We study the phase transition between a normal and a superfluid phase in a prototype system of driven-dissipative bosons on a lattice. This transition is characterized by a finite-frequency criticality corresponding to the spontaneous break of time-translational invariance, which has no analog in equilibrium systems. Later, we discuss the mean-field phase diagram of a Mott insulating phase stabilized by dissipation, which is potentially relevant for ongoing experiments. Our results suggest that there is a trade off between the fidelity of the stationary phase to a Mott insulator and robustness of such a phase at finite hopping. Finally, we present some developments towards using dynamical mean field theory (DMFT) for studying driven-dissipative lattice systems. We introduce DMFT in the context of driven-dissipative models and developed a method to solve the auxiliary problem of a single impurity, coupled simultaneously to a Markovian and a non-Markovian environment. As a test, we applied this novel method to a simple model of a fermionic, single-mode impurity

Abstract:
In the first part of this thesis, a new method is proposed to circumvent the relaxation bottleneck that prevents high-temperature Bose-Einstein condensation of microcavity polaritons. This is achieved by relaxing polaritons with a coherent beam of phonons that is pumped in the growth direction of the quantum well. By tuning the frequency of these phonons to the energy difference between the bottleneck distribution and the ground state, resonant scattering relaxes the exciton reservoir very efficiently. Within a simple rate equation model, it is shown that above a threshold phonon intensity, an unstable and faster-than-exponential instability of the ground state population occurs, with macroscopic occupation possible on sub-picosecond timescales. Numerical results for GaAs and CdTe are presented, confirming that this method could be highly effective in alleviating the bottleneck effect. The second part addresses the problem of decoherence in the sub-Ohmic spin boson model. This previously unimportant model has recently attracted attention due to the discovery of several new physical realisations. Using Silbey and Harris’ variational method, a zero-temperature phase transition between coherent and incoherent ground states is found. The critical spin-bath coupling is extracted, and found to agree well with numerical calculations. Calculations at finite temperatures also yield transitions between coherent and incoherent spin dynamics at a critical temperature. Considering the dynamics of the variational Hamiltonian, it is shown that fluctuations of the bath lead to damping of the coherent spin-dynamics. Approaching the incoherence transition, these dynamics become highly non-Markovian. This chapter also contains a formal demonstration that an alternative variational state, the displaced-squeezed state (DSS), leads to incorrect results in the thermodynamic limit.

Abstract:
Strong coupling between a quantum system and its many-body environment is becoming an increasingly important topic for many branches of physics. Numerous systems of experimental and technological relevance demonstrate strong system-environment coupling, leading to complex dynamical behaviour. This thesis is concerned with two particular examples of such systems, namely quantum dots (QDs) and excitonic energy transfer (EET) in molecular systems. Traditional quantum optics treatments are often insufficient to describe the transient, steady state, and optical properties of QDs due to system-environment correlations. In contrast, we present a modified theory of quantum optics capable of capturing the influence of a thermal environment on the behaviour of QDs. Using this framework we demonstrate a striking departure of the emission spectra and photon measurement statistics of a classically driven QD when compared to an analogous atomic system. Furthermore, in contradiction to accepted notions of decoherence and dissipation, we show that the interaction between a QD and its thermal environment induces non-classical light-matter correlations in an otherwise semi-classical regime of cavity quantum electrodynamics. Away from QDs, we develop the reaction coordinate (RC) formalism to describe the dynamics of a system coupled to a low frequency environment - a regime important to EET systems. We do so by identifying and incorporating important environmental degrees of freedom into an enlarged system Hamiltonian. Uniquely, this approach gives insight directly into the dynamical evolution of the environment and correlations accumulated between the system and environment. Furthermore, it is demonstrated that these corre- lations persist into the steady state, generating non-canonical equilibrium states of the system and environment. We then apply the RC model to describe EET in a molecular dimer, highlighting the effect that under- and over-damped environments have on the excitation dynamics. In doing so, we show interactions between the dimer and a structured environment can significantly enhance the energy transfer rate.

Abstract:
Motivated by the continuous advancements in the miniaturization of devices down to reveal the quantum nature of matter, in this thesis we investigate the way a quantum system is affected by the presence of a thermal environment and propose methodologies to exploit this kind of sensitivity for quantum technologies. Since treating exactly the dynamics of the full system-environment compound is generally problematic for the diverging number of degrees of freedom involved in the calculation, effective master equations for the reduced system density matrix were developed in literature during the last century. Among them, the Redfield approach is an equation obtained under weakcoupling (or Born) and Markovian assumptions. Despite offering effective descriptions in a plethora of situations, it was criticized for not preserving the positivity (and hence the complete positivity) of the system density matrix. The latter property is in general a fundamental feature for assigning a probabilistic interpretation to the theory. We hence begin by facing the problem of the non-positivity character of the Redfield equation, curing it of the strict amount that is necessary via coarse-grain averaging performed on the Redfield equation in the interaction picture. In the analysis a central role is played by the coarse grain timescale. Once set it equal to a critical threshold value, the resulting equation (CP-Redfield) enables conserving the predictive power of the Redfield approach and preserving positivity at the same time. About it, we report both practical estimation and self-consistent methods to evaluate the critical timescale. Our strategy also allows to continuously map the Redfield equation into the secular master equation (diverging coarse-grain time interval) by appropriately tuning the coarse grain time, the latter being the equation usually adopted in the literature for ensuring thermodynamic consistency by enforcing a rotating-wave approximation. Starting from a minimal example concerning the dipole coupling between a qubit and a bosonic bath, we then apply this methodology to dissipative multipartite systems, for which the local vs global debate is of current interest. The local master equation is instead the equation that is obtained by assigning to each subsystem its proper thermal dissipator, preserving the local character of the microscopic interactions, while the global approach is the Redfield equation in the secular limit. In this context, we studied an asymmetric energy transfer model constituted by harmonic oscillators which, being exactly solvable, provides the appropriate benchmark for testing the efficiency of the different master equations.. Beyond finding useful the application of the CP-Redfield equation, we point out a sensible convex-mixture of the local and global solutions based on the timescale separation of the two strategies. The local approach is then applied in the context of quantum batteries, a field that was previously analyzed under closed (i.e. Hamiltonian) settings. We hence provide one of the first attempts of schematizing an open quantum battery, where, recalling in part the aforementioned asymmetric model, the charging process originates from external sources (coherent and/or noisy) and is mediated by a proper quantum charger. By studying different implementations, particular attention was devoted to find possible interplay between coherent and incoherent energy supply mechanisms in producing stored energy and ergotropy, the latter being defined in literature as the maximum extractable work. As a central result, increasing temperature is not always detrimental for the stored ergotropy. Going beyond the particular instance of bosonic bath, the sensitivity of a quantum system to its surrounding environment is finally exploited in the context of statistical tagging, where one aims to guess the quantum statistics (fermionic or bosonic) of a thermal bath of interest, introducing in this way a novel research line in the field of quantum metrology. We propose an indirect measurement protocol in which a quantum probe is let to interact with the unknown bath and relies on the consideration that, despite the final probe equilibrium configuration is not necessarily influenced by the bath nature, the latter generally leaves residual imprintings in the probe state before thermalization, i.e. out-of-equilibrium. Using figures of merit taken from quantum metrology such as the Holevo-Helstrom probability of error and the quantum Chernoff bound, we treated the cases of qubit and harmonic oscillator probes, finding that, generally, the presence of coherences in the input state of the probe is beneficial for the discrimination capability and noticing a bosonic advantage in reducing to zero the error probability.

Abstract:
This thesis probes the usefulness of non-classical correlations within imperfect continuous variable decoherent quantum systems. Although a consistent function and practical usefulness of these correlations is largely unknown, it is important to examine their characteristics in more realistic dissipative systems, to gain further insight into any possible advantageous behaviour. A bipartite separable discordant state under the action of controlled loss on one subsystem was considered. Under these conditions the Gaussian quantum discord not only proved to be robust against loss, but actually improves as loss is intensified. Harmful imperfections which reduce the achievable level of discord can be counteracted by this controlled loss. Through a purification an explanation of this effect was sought by considering system-environment correlations, and found that a flow of system-environment correlations increases the quantumness of the state. Entanglement recovery possibilities were discussed and revealed the importance of hidden quantum correlations along bi-partitions across the discordant state and a classically prepared "demodulating" system, acting in such a way as to partially cancel the entanglement preventing noise. Entanglement distribution by separable states was studied by a similar framework, in an attempt to explain the emergence of quantum entanglement by a specific flow of correlations in the globally pure system. Discord appears to play a less fundamental role compared to the qubit version of the protocol. The strengthening of non-classical correlations can be attributed to a flow of classical and quantum correlations. This work proves that discord can be created in unique ways and, in select circumstances, can act to counteract harmful imperfections in the apparatus. Due to this advantageous behaviour discord indeed may ultimately aid in more applicable "real world" applications, which are by definition decoherent.

Abstract:
It is well known that two ideally confident surfaces should give the effect of superlubricity, e.g. should slide without friction. In principle, the superlubricity deals with absence of energy dissipation mechanism. If we consider interatomic interactions, we see that the number of atoms, which resist sliding is equal to the number of atoms that push slider. In the case of noncontact quantum friction interacting surfaces are divided by some spatial interval. This sliding can take place in probe (atomic force or scanning tunneling) microscopy. However, experiments usually show nonzero friction force in this case. Nowadays there are several mechanisms of the noncontact friction. According to all of these models the noncontact friction arises from photons momentum transfer between surfaces. But there is much more efficient mechanism of noncontact friction dealing with electron tunneling. Two tunneling electron flows or tunneling currents between close conductive surfaces transmit momentum from a moving body (slider) to the fixed one (substrate) and at the same time in backward direction. At the thermodynamic equilibrium conditions these two counter-flows are equal. We have calculated these flows. Two different approaches have been applied — quantum mechanical and quasi-classical ones. The complex shape of the sliding surface have been taken into account by introduction of special function for the distribution of the tunneling gap width. In this model, noncontact friction is similar to Newtonian viscous friction in the fluid. Friction force has been calculated for both variants. Numerical evaluations according to both formulas have shown rather similar results. It has been found that in both cases friction force is proportional to the slider’s speed and exponentially decreases with increase of the tunneling gap. In addition, the friction force disappears at zero temperature. The tangential stresses have been obtained from numerical calculations for different surfaces with different roughness and for the atomically smooth surfaces. These values are close to macroscopic friction stress in experiments.

Abstract:
We present a novel nonlinear optical effect which arises in a spatial structure of electromagnetic field. Our analysis establishes also, for the first time, a link between the fields of spatial instabilities [1] and of quantum noise reduction [2,3], in nonlinear optical systems.
