Cosmology, Decoherence and the Second Law
Sebastian Cespedes, Senarath de Alwis, Fernando Quevedo
We consider quantum decoherence and entropy increase in early universe cosmology. We first study decoherence in a discrete bipartite quantum system for which a single qubit gets en…
Moduli Stabilization in String Theory
Liam McAllister, Fernando Quevedo
We give an overview of moduli stabilization in compactifications of string theory. We summarize current methods for construction and analysis of vacua with stabilized moduli, and w…
A Comment on Continuous Spin Representations of the Poincaré Group and Perturbative String Theory
Anamaria Font, Fernando Quevedo, Stefan Theisen
We make a simple observation that the massless continuous spin representations of the Poincaré group are not present in perturbative string theory constructions. This represents on…
On Bouncing Brane-Worlds, S-branes and Branonium Cosmology
C. P. Burgess, F. Quevedo, R. Rabadan +2
We present several higher-dimensional spacetimes for which observers living on 3-branes experience an induced metric which bounces. The classes of examples include boundary branes…
S-Branes, Negative Tension Branes and Cosmology
F. Quevedo, G. Tasinato, I. Zavala
A general class of solutions of string background equations is studied and its physical interpretations are presented. These solutions correspond to generalizations of the standard…
