虫洞的热力学稳定性

Thermodynamic Stability of Wormholes

S. N. Sajadi, N. Riazi

摘要:

在广义相对论的背景下,我们研究了洛伦兹虫洞在视视界处的热力学稳定性。各向异性组分的平均压力被认为是虫洞的压力。根据常规热力学中稳定平衡的要求,计算了虫洞的定压热容和吉布斯自由能,分析了虫洞的局部和全局热力学稳定性。

英文摘要:

In the context of GR, we study the thermodynamic stability of evolving Lorentzian wormholes at the apparent horizon. The average pressure of the anisotrropic components is considered as the pressure of the wormhole. According to the requirements of stable equilibrium in conventional thermodynamics, we calculate the heat capacity at constant pressure and Gibbs free energy and analyze the local and global thermodynamic stability of the wormhole.
