Several microscopic theories point out that Bose-Einstein condensation (BEC), i.e., a macroscopic occupation of the lowest energy single particle state in many-boson systems, may appear also in quantum ...
Trefzger, Christian (Data de defensa: 2010-04-19)
Esta tesis es un trabajo teórico, en el que estudiamos la física de los átomos dipolares bosónicos ultrafríos en retículos ópticos. Éstos gases consisten de átomos o moléculas bosónicas, enfriados bajo ...
Vito, Roppo (Data de defensa: 2011-06-15)
In the field of second harmonic (SH) generation most studies have been concerned with maximizing conversion efficiencies, generally achievable at the phase matching (PM) condition. Outside of the PM the ...
Lorente Espín, Oscar (Data de defensa: 2012-09-20)
In this thesis we have focused on semi-classical methods that enables us to obtain non-thermal spectra for the vast majority of black holes. This fact is due to taking into account the backreaction of ...
Suñol Galofré, Francesc (Data de defensa: 2011-07-19)
Two-phase flows are encountered in a wide range of applications both on-ground and in space. The dynamics of such flows in the absence of gravity is completely different from that in normal gravity due ...
Tiana Alsina, Jordi (Data de defensa: 2011-11-10)
The purpose of this Thesis is study the dynamical behavior of semiconductor lasers with optical feedback, as well as analyze the synchronization of this kind of systems under different coupling ...
López Alonso, José Manuel (Data de defensa: 2015-02-05)
Despite the large amount of research which has been conducted on turbulent flows, a full understanding of their dynamics as well as the mechanisms involved in the onset of turbulence is still missing. ...
Panadès i Guinart, Carles (Data de defensa: 2013-06-28)
Even though the transition to turbulence has been studied for over a century, its complete comprehension still remains unclear even for the simplest flows and continues to be a daunting challenge for ...
Rovira Esteva, Muriel (Data de defensa: 2014-09-26)
Neutron diffraction is a powerful technique that allows to probe the structure of disordered phases across a variety of length scales. However, due to the inherent complexity of these disordered hases, ...
Blay Carreras, Estel (Data de defensa: 2014-07-21)
The atmospheric boundary layer is the part of the troposphere influenced by the presence of the surface, and where most weather phenomena occur. During the day, with fair weather conditions, a convective ...
