Holographic Entanglement Entropy for Excited States in Two Dimensional CFT

Amin Faraji Astaneh, Amir Esmaeil Mosaffa

We use holographic methods to study the entanglement entropy for excited states in a two dimensional conformal field theory. The entangling area is a single interval and the excita…

Holographic Phase Transition to Topological Dyons

Davood Allahbakhshi, Farhad Ardalan

The dynamical stability of a Julia-Zee solution in the AdS background in a four dimensional Einstein-Yang-Mills-Higgs theory is studied. We find that the model with a vanishing sca…

On Born-Infeld Gravity in Three Dimensions

Mohsen Alishahiha, Ali Naseh, Hesam Soltanpanahi

In this paper we explore different aspects of three dimensional Born-Infeld as well as Born-Infeld-Chern-Simons gravity. We show that the models have AdS and AdS-wave vacuum soluti…

3-Form Flux Compactification of Salam-Sezgin Supergravity

Hamid Reza Afshar, Shahrokh Parvizi

The compactification of 6 dimensional Salam-Sezgin model in the presence of 3-form flux H is investigated. We find a torus topology for this compactification with two cusps which a…
