Temperature of wormhole with exotic matter

Abstract

We study (3+1) Morris-Thorne wormhole to investigate its higher dimensional embedding structures and thermodynamic properties. It is shown that the wormhole is embedded in (5+2) global embedding Minkowski space. This embedding enables us to construct the wormhole entropy and wormhole temperature by exploiting Unruh effects. We also propose a possibility of negative temperature originated from exotic matter distribution of the wormhole. © 2005 by World Scientific Publishing Co. Pte. Ltd. All rights reserved.
