Entanglement Entropy at Large-N
P Talavera
I show that at early times the evaporation process for a stack of NS5-branes at high energy is suppressed in the large-N limit. At much later times, the new saddles in the gravitat…
Enhanced symmetry and Entropy of Schwarzschild-deSitter spacetime
D. Guerrero-Dominguez, P. Talavera
In this paper we show that the equation of motion of a massless scalar particle near the black hole (BH) horizon in the Schwarzschild-deSitter (SdS) spacetime enjoys a hidden confo…
On cosmological expansion and local physics
J. M. Pons, P. Talavera
We find an exact convergence in the local dynamics described by two supposedly antagonistic approaches in modern cosmology: one starting from an expanding universe perspective such…
One-loop Parke-Taylor factors for quadratic propagators from massless scattering equations
Humberto Gomez, Cristhiam Lopez-Arcos, Pedro Talavera
In this paper we reconsider the Cachazo-He-Yuan construction (CHY) of the so called scattering amplitudes at one-loop, in order to obtain quadratic propagators. In theories with co…
Normalizable fermion modes in a holographic superconductor
Steven S. Gubser, Fabio D. Rocha, Pedro Talavera
We consider fermions in a zero-temperature superconducting anti-de Sitter domain wall solution and find continuous bands of normal modes. These bands can be either partially filled…
A silence black hole: Hawking radiation at the Hagedorn temperature
O. Lorente-Espin, P. Talavera
We compute semi-classically the Hawking emission for different types of black hole in type II string theory. In particular we analyze the thermal transition between NS5 branes and…
