Interplay of spin-orbital correlations and structural distortions in Ru- and Cr- based perovskite systems
(Universita degli studi di Salerno, 2012-07-02)
The transition metal oxides are emerging as the natural playground where the intriguing effects
induced by electron correlations can be addressed. Since the s electron of the transition metals
are transferred to the ...
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 ...
Exact solutions in general relativity and alternative theories of gravity: mathematical and physical properties
(Universita degli studi di Salerno, 2011-06-06)
In this thesis, we discuss several subjects connected with the framework
of GR, in order to characterize astrophysical compact objects. The main
purpose is to provide simple models describing gravitational fields generated ...
Investigation of the groundwater-river interaction, using Radon-222 as a natural tracer, in a karst Mediterranean environment like in the case study of the Bussento river basin
(Universita degli studi di Salerno, 2010-04-27)
The naturally-occurring radionuclides have proven to be powerful tools for assessing the time dependency of GSI processes. The radionuclide 222Rn (referred to as radon) has the advantage of being a radioactive noble gas, ...
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 ...
An insight into gravitational microlensing and the search for exoplanetary systems
(Universita degli studi di Salerno, 2015-04-30)
Nature always offers astonishing shows to the humankind. Gravitational lensing is one of the most intriguing effects which can be observed, and the astrophysical applications of such a phenomenon span from particle physics ...
A study on iron-chalcogenides superconductors: from samples preparation to physical properties
(Universita degli studi di Salerno, 2017-03-14)
In the scientific community there is a great interest to explore new superconducting materials suitable for high field applications in order to meet the needs of industrial claims. In this framework, newly discovered ...
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 ...
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 ...
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, ...
