论文摘要
我们研究动态遍历虫洞的热力学。这些虫洞在不同的宇宙学模型的背景下进行了研究，具有或不具有宇宙学的常数，其中还包括幂律和指数宇宙学。我们为不同形状的虫洞构成了广义的表面重力。在捕获范围内评估表面重力，并建立了热力学的统一第一定律。这些虫洞的热力学稳定性也已经进行了研究。也已经考虑了某些渐近平坦，de保姆和抗DE保姆虫洞的情况。我们的结果概括了静态莫里斯 - thorne虫洞存在的结果。
We study thermodynamics of dynamical traversable wormholes. These wormholes are investigated in the background of different cosmological models, with and without the cosmological constant, and which include the power-law and exponential cosmologies also. We work out the generalized surface gravity for wormholes of different shapes. The surface gravity is evaluated at the trapping horizon and the unified first law of thermodynamics is set up. The thermodynamic stability of these wormholes has also been investigated. Some cases of asymptotically flat, de Sitter and anti-de Sitter wormholes have been considered as well. Our results generalize those that exist for static Morris-Thorne wormholes.
