Rotating traversable wormholes in AdS

TL;DR

This paper investigates how rotation affects the size and information capacity of traversable wormholes in AdS space, showing that increased angular momentum enlarges the wormhole and enhances information transfer, but it closes near extremal temperatures.

Contribution

It demonstrates the impact of rotation on traversable wormholes in AdS, including size, information transfer, and effects of boundary coupling inhomogeneity.

Findings

Wormhole size increases with angular momentum at fixed temperature.

Information transfer capacity of the wormhole increases with rotation.

Wormhole closes as temperature approaches extremal limit.

Abstract

In this work we explore the effect of rotation in the size of a traversable wormhole obtained via a double trace boundary deformation. We find that at fixed temperature the size of the wormhole increases with the angular momentum $J/M\ell$. The amount of information that can be sent through the wormhole increases as well. However, for the type of interaction considered, the wormhole closes as the temperature approaches the extremal limit. We also briefly consider the scenario where the boundary coupling is not spatially homogeneous and show how this is reflected in the wormhole opening.
