洛伦兹虫洞进一步推广了热力学

Lorentzian wormholes generalizes thermodynamics still further

Prado Martin-Moruno, Pedro F. Gonzalez-Diaz

摘要:

本文讨论了洛伦兹虫孔的一些物理问题,包括三个主要定律的表述和考虑了一种可能的热发射,这种热发射是由某种在负温度下从虫孔中出来的幻影辐射组成的。为了使这些主题得到一致的发展,我们使用了2+2形式主义首先先进的海沃德球对称时空,广义表面引力被定义在捕获的地平线上。我们的结果进一步推广了已经推广的引力热力学。

英文摘要:

This paper deals with some thermodynamical aspects of Lorentzian wormholes, including the formulation of the three main laws and the consideration of a possible thermal emission made up of some sort of phantom radiation coming out from the wormhole at a negative temperature. In order for these topics to be consistently developed we have used a 2+2 formalism first advanced by Hayward for spherically symmetric space-times, where a generalized surface gravity is defined on the trapping horizon. Our results generalize still further those of the already generalized gravitational thermodynamics.
