Asymptotically Lifshitz Brane-World Black Holes

TL;DR

This paper investigates Lifshitz black holes within a brane-world framework, analyzing their thermodynamics, stability, and phase transitions, revealing bounds on the critical exponent and conditions for positive entropy.

Contribution

It introduces a study of Lifshitz black holes in a brane-world scenario considering extra-dimensional effects and thermodynamic properties.

Findings

Entropy bounds the critical exponent z from above.

Maximum z corresponds to infinite entropy at positive temperature.

Stability and phase transitions depend on spatial topology.

Abstract

We study the gravity dual of a Lifshitz field theory in the context of a RSII brane-world scenario, taking into account the effects of the extra dimension through the contribution of the electric part of the Weyl tensor. We study the thermodynamical behavior of such asymptotically Lifshitz black holes. It is shown that the entropy imposes the critical exponent $z$ to be bounded from above. This maximum value of $z$ corresponds to a positive infinite entropy as long as the temperature is kept positive. The stability and phase transition for different spatial topologies are also discussed.
