Electric transport properties of S/F hybrids: weak and inhomogenous ferromagnet
(Universita degli studi di Salerno, 2012-03-30)
Superconductivity (S) and ferromagnetism (F) are competing phases whose coexistence
is unlikely to occur. Exceptions require a non−uniform profile both for the pairing and the
magnetization, as in the case of the FFLO ...
Nb nanoporous ultrathin films: matching effects and interconnected wires
(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 ...
Dissipation, mixing and two level system in quantum field theory
(Universita degli studi di Salerno, 2012-04-30)
In this dissertation we discuss several aspects of a two level system (qubit) in the context of quantum mechanics and quantum field theory. The presence of geometrical phases in the evolution of a qubit state is shown. We ...
Magneto-transport properties of thin superconducting strips in the framework of Time Dependent Ginzburg Landau model
(Universita degli studi di Salerno, 2012-05-30)
This dissertation is addressed to summarize my experimental/phenomenological research
activities conducted at the laboratories of Physics Department, University of Salerno. The
experimental work consisted in the fabrication ...
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, ...
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 ...
Magnetic orbital and transport properties in LaMnO3 based based heterostructures
(Universita degli studi di Salerno, 2011-05-13)
This thesis work deals with the magnetic, orbital and transport properties of (LaMnO3)2N(SrMnO3)N digital superlattices and of LaxMnO3-d thin films, both deposited by molecular beam epitaxy (MBE) technique on SrTiO3 ...
The neutrino interaction analysis chain in OPERA
(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 ...
Detailed study of local and regional seismicity recorded by the underground UNDERSEIS array at Gran Sasso (Central Italy)
(Universita degli studi di Salerno, 2011-05-13)
In this work I analyzed seismic data recorded by two arrays installed in the area of Mt. Gran Sasso
(Central Italy), one located at 1.4 km depth (UNDERSEIS), and the other at surface (Fontari). The
aim is to compare the ...
Improvements in the acoustical modelling of traffic noise prediction: theoretical and experimental results
(Universita degli studi di Salerno, 2011-04-21)
Traffic acoustical noise is one of the most important component of the urban environmental pollution in densely populated areas all over the world.
A very recent ACI-Censis study [1] on Italian urban areas shows that car ...
