    • Nb nanoporous ultrathin films: matching effects and interconnected wires 

      Trezza, Michele (Universita degli studi di Salerno, 2012-03-03)
      When the applied magnetic field is higher than the lower critical field but below the upper critical field, a type-II superconductor allows magnetic flux to penetrate it in the form of vortices, a tiny normal area ...
    • The neutrino interaction analysis chain in OPERA 

      Rescigno, Regina (Universita degli studi di Salerno, 2011-04-20)
      The aim of the OPERA experiment is to provide a “smoking-gun” proof of neutrino oscillations, through the detection of the appearance signal of ντ’s in an initially pure νμ beam. The beam is produced at CERN, 732 Km far ...
    • Non-markovian quantum dynamics 

      Torre, Gianpaolo (Universita degli studi di Salerno, 2016-04-28)
      Quantum systems can necessarily be viewed as open systems. As in classical physics, any realistic description of a system must take into account the cou- pling to an environment that strongly in uences the system itself. ...
    • On neutrino mixing in Quantum Field Theory 

      Gargiulo, Maria Vittoria (Universita degli studi di Salerno, 2017-05-23)
      Neutrino physics is one of the most important areas in research on the fundamental interactions, both theoretically and experimentally. A central issue in the study of these particles is related to the properties of mixing ...
    • Particle mixing, two level systems and gauge theory 

      Raimondo, Gianluca (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 

      Guarnaccia, Giuseppe (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. 

      Vanacore, Antonio (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 

      Cianciaruso, Marco (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 

      Di Giorgio, Cinzia (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 

      Annunziata, Gaetano (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 

      Sorgente, Alessandro (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 ...
