Accurate mesurements of spectroscopic line parameters of atmospheric relevant molecules
(Universita degli studi di Salerno, 2017-07-14)
This thesis deals with the development of frequency-stabilized laser absorption spectrometers in the near-infrared to perform precision measurements on molecular spectra of atmospheric interest, such as acetylene and ...
On neutrino mixing in Quantum Field Theory
(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 ...
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 ...
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 ...
Crystal growth and physical properties of helimagnetic oxides
(Universita degli studi di Salerno, 2017-07-13)
This work is focused on two helimagnetic materials: Ba2CuGe2O7 and Cu3Nb2O8. Recent studies report a number of interesting anisotropic proper- ties [1, 2, 3]. Ba2CuGe2O7 melilite oxide shows a complex magnetic behaviour, ...
Flavor mixing in quantum field theory and quantum information
(Universita degli studi di Salerno, 2011-05-10)
After reviewing the formalism for describing flavor mixing, both in Quantum Mechanics and Quantum Field Theory, some consequences along three different directions are studied. First, it is proposed that flavor mixing can ...
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 , conventional superconductors are classified in type I and type II, based on the value the G-L parameter... [edited by author]
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 ...
Influence of grains on the electromagnetic ac response of superconducting materials
(Universita degli studi di Salerno, 2016-04-20)
Type II superconducting materials are technologically interesting since they are characterized by the existence of a superconducting phase even after the penetration of the magnetic field inside them. In fact, while type ...
Constraining models of extended theories of gravity with terrestrial and astrophysical experiments
(Universita degli studi di Salerno, 2015-04-30)
In this Thesis we report a general review of Extended Theories of Gravity and the fundamental aspects of General Relativity. We show the technicality of development of field equation with respect to Newtonian, Post-Newtonian ...
