在高维宇宙学中相互作用的Tsallis全息暗能量

Interacting Tsallis holographic dark energy in higher dimensional Cosmology

A. Saha, S. Ghose

摘要:

讨论了高维Tsallis全息暗能量(THDE)模型.在紧致Kaluza-Klein引力框架下,利用广义Chaubergin气体(GCG)提出了一个相互作用的暗能量模型.结果表明,一个稳定的配置可以找到在本历元,这也是兼容的密度参数的观测值。值得注意的是,暗能量(DE)可能是从过去的幻影阶段演变而来的。发现暗能量的性质依赖于相互作用的耦合参数。经典的稳定性考虑也被发现把一个上限的模型参数。

英文摘要:

We discuss Tsallis holographic dark energy (THDE) model in higher dimension. An interacting dark energy model is proposed with Generalized Chaplygin Gas (GCG) in the framework of Compact Kaluza-Klein gravity. It is shown that a stable configuration can be found in the present epoch which is also compatible with the observed value of the density parameter. It is noted that dark energy (DE) might have evolved from a phantom phase in the past. Nature of dark energy is found to depend on the coupling parameter of the interaction. Classical stability consideration is also found to put an upper bound on the model parameter.
