新全息暗能量模型与广义热力学第二定律相互作用的状态发现和Om诊断
Statefinder and Om Diagnostics for Interacting New Holographic Dark Energy Model and Generalized Second Law of Thermodynamics
摘要：
在这项工作中，我们考虑了平坦的FRW宇宙充满了暗物质和新的全息暗能量的混合物。如果存在相互作用，我们研究了减速参数、状态发现器和$Om$诊断的性质。我们在事件和视视界上检验了在这些相互作用下热力学第一和广义热力学定律的有效性。已经观察到，在事件视界上违反第一定律。然而，广义第二定律在整个被视视界包围的宇宙演化过程中都是有效的。当把事件视界看作是包络视界时，发现广义第二定律除了在宇宙的晚期外，都是不成立的。
英文摘要：
In this work, we have considered that the flat FRW universe is filled with the mixture of dark matter and the new holographic dark energy. If there is an interaction, we have investigated the natures of deceleration parameter, statefinder and $Om$ diagnostics. We have examined the validity of the first and generalized second laws of thermodynamics under these interactions on the event as well as apparent horizon. It has been observed that the first law is violated on the event horizon. However, the generalized second law is valid throughout the evolution of the universe enveloped by the apparent horizon. When the event horizon is considered as the enveloping horizon, the generalized second law is found to break down excepting at late stage of the universe.
