Montejo Estevez, Manuel (Data de defensa: 1999-11-09)
El objetivo de esta tesis es construir un modelo cuántico para las ondas gravitatorias planas, unas soluciones de vacío de las ecuaciones de Einstein que presentan simetrías análogas a las ondas ...
Fröb, Markus Benjamin (Data de defensa: 2013-12-09)
In this thesis we studied quantum effects in de Sitter space coming from the interaction of gravitons and matter. We derived the lowenergy effective action for metric perturbations which includes ...
Arteaga Barriel, Daniel (Data de defensa: 2007-06-28)
The basic aim of the thesis is the study of the propagation of particles and quasiparticles in non-trivial backgrounds from the quantum field theory point of view. By "non-trivial background" we mean ...
