Particle mixing, two level systems and gauge theory
(Universita degli studi di Salerno, 2012-04-26)In this thesis I will discuss the theory of two level systems and the theory of the oscillating particles in quantum eld theory. In the rst chapter I will consider the time evolution of a two level system, a qubit, ... -
Phase transitions in strongly correlated electronic systems
(Universita degli studi di Salerno, 2014-06-19)We studied the some type of phase transitions in Strongly Correlated Electronic Systems. In particular we rigorously established some exact properties of a multi-orbital Hubbard model, here formulated to describe a nematic ... -
Progettazione e sperimentazione di un percorso didattico sperimentale in superconduttività.
(Universita degli studi di Salerno, 2014-07-31)Vengono presentate e discusse le fasi di progettazione, realizzazione e valutazione di efficacia di un percorso didattico di insegnamento/apprendimento incentrato sui materiali superconduttori partendo dalle loro proprietà ... -
Signatures of quantumness: identification, quantification and dynamical preservation
(Universita degli studi di Salerno, 2016-04-14)The quanti cation of quantumness is necessary to assess how much a physical system departs from a classical behaviour and thus gauge the quantum enhancement in opera- tional tasks such as information processing and ... -
Superconductivity in S/F hybrids: a Scanning Probe Microscopy study of orbital interaction
(Universita degli studi di Salerno, 2016-04-14)In the framework of the Ginzburg-Landau (G-L) theory [1], conventional superconductors are classified in type I and type II, based on the value the G-L parameter... [edited by author] -
Transport and proximity effect in unconventional ferromagnet/superconductor heterostructures
(Universita degli studi di Salerno, 2011-05-30)This dissertation collects results of my own work about heterostructures with unconventional ferromagnets and superconductors. It both introduces the matter by reviewing part of the existing literature and it includes ... -
Trasporto quantistico di spin in eterostrutture magnetiche
(Universita degli studi di Salerno, 2012-06-04)In questa tesi abbiamo studiato il trasporto di spin polarizzato e la torsione dello spin usando l’apporoccio della matrice di scattering secondo la teoria di Buttiker, nel caso di barriere magnetiche finite sotto l'effetto ...
