Aspects of quantum gravity in AdS3/CFT2
(2019)
The quest for finding a unifying theory for both quantum theory and gravity lies at the
heart of much of the research in high energy physics. Although recent years have witnessed
spectacular experimental confirmation of ...
Bayesian analysis and constraints on kinematic models from union SNIa
(IOP PUBLISHING LTD, 2009)
The kinematic expansion history of the universe is investigated by using the 307 supernovae type Ia from the Union Compilation set. Three simple model parameterizations for the deceleration parameter ( constant, linear and ...
Teoria de redes no espaço hiperbólico e aplicações
(Universidade Federal de PernambucoUFPEBrasilPrograma de Pos Graduacao em Matematica, 2019)
D-oscillons in the standard model extension
(Amer Physical Soc, 2015-06-17)
In this work we investigate the consequences of the Lorentz symmetry violation on extremely long-lived, time-dependent, and spatially localized field configurations, named oscillons. This is accomplished for two interacting ...
The warped dark sector
(2019-11-10)
Five-dimensional braneworld constructions in anti-de Sitter space naturally lead to dark sector scenarios in which parts of the dark sector vanish at high 4d momentum or temperature. In the language of modified gravity, ...
Entanglement generated by a Dicke phase transition
(2000)
In the framework of nonassociative geometry a unified description of continuum and discrete spacetime is proposed. In our approach at the Planck scales the spacetime is described as a so-called diodular discrete structure ...
Matching between supersymmetric effective theory of inflation and pure de Sitter SUGRA
(Departamento de FísicaUniversidad Nacional de Colombia - Sede Bogotá, 2019-09-11)
Several models of inflationary cosmology have been recently established. They provide a wide and rich field of research where most of the predictions are meant to be tested within the next generation of cosmological ...
Generación de campos magnéticos primordiales
(2011-04)
La explicación del origen de campos magnéticos galácticos y extra galácticos sigue siendo un problema sin resolver en la cosmología actual. Una posible explicación viene en el hecho de que dichos campos surgieron a partir ...
