Abstract:
Quantum spin liquids (QSLs) are strongly correlated systems displaying fascinating phenomena like long-range entanglement and fractionalized excitations. The research on these states has since its beginning followed trends generated by the synthesis of new compounds and the construction of new theoretical tools. In coherence with this history, a manifold of new results about QSLs were established during the past decade due to studies on the integrable Kitaev model on the honeycomb lattice. This j = 1/2 model displays bond-dependent and anisotropic exchanges that are essential to stabilize its

Il presente lavoro di tesi si prefigge di fornire uno studio della teoria alla base della descrizione di una particella di spin 2 massiva, attraverso la teoria dei campi quantistici. Dopo una dettagliata derivazione del modello, il lavoro si concentra sullo studio di due possibili costruzioni che differiscono tra loro per una diversa struttura dell'accoppiamento tra la particella di spin 2 e il resto del Modello Standard (MS). In particolare la differenza consiste nel fatto che, nel primo caso la costante di accoppiamento è universale mentre nel secondo modello l'accoppiamento con ogni campo d

Abstract During the past decade submicron and nanoparticles have aroused a wide interest and gained new applications due to their high surface area and strength. Grinding with a wet stirred media mill is usually the last process step before the submicron or nanoparticles are added to an application, and the step where the final particle size distribution is achieved. Since stirred media milling is an energy-intensive process, energy efficiency should be optimized. This can be done by determining the optimum operational parameters for the mill and using the highest possible solids concentration

Abstract:
For several years Metastable Atom Deexcitation Spectroscopy (MDS) has been employed as a probe of surface electronic structure offering unparalleled surface specificity. In MDS a thermal-energy beam of rare-gas metastable atoms is directed at the surface under study, and the energy distribution of electrons ejected as a result of metastable atom deexcitation is measured. However, correct interpretation of the data requires detailed knowledge of the dynamics of the deexcitation process. In the present work spin-labeling techniques, specifically the use of electron-spin-polarized metastable He(2

I will rst do two brief examples, where we will compute the QNMs for a scalar eld in a Schwarzschild and Reissner-Nordstr=om background, then the QNMs for a massless Dirac spinor in a Schwarzschild background. These two examples will help build some intuition le

Abstract:
The present PhD thesis describes the synthesis and characterisation of Co(2+/3+) complexes with triarylamine-substituted polypyridyl-based ligands. A light- or temperature-induced intramolecular electron transfer between the Co and the triarylamine moieties was found in the tri-cationic complexes, which was examined with electrochemical measurements, DFT calculations, optical and dynamic 1H NMR spectroscopy. This process is coupled to a high-spin <--> low-spin transition on the metal. The emphasis of this PhD thesis was the adjustment of a redox equilibrium between the paramagnetic ([Co2+(L+)(

Abstract:
Femtosecond electron diffraction experiments were performed on solid state iron(II) tris(2,2'-bipyridine) bis(hexafluorophosphate). The cation is known to undergo a spin crossover process when solvated in water and irradiated with 400 nm coherent light which results in a transition from a low spin to high spin state within a picosecond which is accompanied by a uniform 0.2 Å Fe-N bond elongation. A femtosecond diffraction experiment was performed on the solid sample and was unable to find evidence of a fast spin crossover transition. Suspecting this may be due to limitations of the apparatus,
