On Vector-Valued Schrodinger Operators in Lp-spaces
(Universita degli studi di Salerno, 2018-04-06)... We construct a realization Ap of A in the spaces Lp(Rd;Cm), 1 p < 1, that generates a contractive strongly continuous semigroup. First, by using form methods, we obtain generation of holomorphic semigroups when the ... -
Orbital motion, periastron advance and galaxy rotation curves beyond General Relativity
(Universita degli studi di Salerno, 2023-01-02)The Extended Theories of Gravity (ETG) have become one of the most investigated the- oretical proposals among the alternative explanations for the observed flatness of galaxy rotation curves, related to the dark matter ... -
Polyhedral analysis and branch and cut algorithms for some NP-hard spanning subgraph problems
(Universita degli studi di Salerno, 2020-01-07)There is a widespread need to use a quantitative approach for the solution of decision problems that arise in many different areas of real life. The goal is to choose which decisions to take to manage a real system as ... -
Praseodymium and manganese doped Ca2RuO4: crystals growth and physical properties
(Universita degli studi di Salerno, 2023-07-17)Layered ruthenates have received a great attention in condensed matter physics due to the richness of their physical properties and the related phase diagram. Ruthenate compounds show a strong interplay between electronic, ... -
Lo pseudotensore energia-impulso in teorie estese della gravitazione
(Universita degli studi di Salerno, 2018-07-12)The gravitational field’s energy and momentum definitions are treated in extensive gravitation theories, through the generalization of the energymomentum pseudotensor, defined by Einstein in general relativity. This ... -
Stochastic processes governed by the generalized telegraph process and by Brownian motion and their applications
(Universita degli studi di Salerno, 2021-06-18)The aim of this research thesis is to broaden the treatment of stochastic processes derived from the telegraph process and Brownian motion. First, the classical telegraph process is presented. The Kolmogorov equations ... -
Tailoring the structural and surface properties of TiO2 thin films and TiO2-based nanolayers, with heat treatments, layer thickness, and oxide mixtures
(Universita degli studi di Salerno, 2021-12-15)Titanium dioxide (TiO2), also known as titanium (IV) oxide or titania, is naturally available on the Earth as a bright, fine, and white pigment. Thanks to its unique properties, such as high refractive index, chemical ... -
Transition Metal Dichalcogenides and Carbon Nanomaterials in Field Effect Devices and Photodetectors
(Universita degli studi di Salerno, 2023-02-20)This PhD thesis focuses on the electronic and optoelectronic characterization of devices based on low-dimensional materials and on a first approach to fabrication of 2D transition metal dichalcogenide (TMD) field effect ... -
Unveiling spin-orbit coupling e ects on the electronic states of multi-orbital Transition Metal Oxides
(Universita degli studi di Salerno, 2018-06-03)Transition Metal Oxides (TMOs) show a wealth of intriguing properties which are governed by the interplay of charge, spin, and orbital degrees of freedom. Moreover, the comprehension of the features of strongly ... -
Λ + c production vs the event charged-particle multiplicity in pp collisions at 13 TeV with ALICE at the LHC
(Universita degli studi di Salerno, 2023-03-22)The Quantum Chromo-Dynamics (QCD) theory predicts, in condition of very high temperature and/or energy density, a phase transition from the ordinary nuclear matter to a colour-deconfined medium called Quark–Gluon Plasma ...
