论文摘要
我们讨论了更高维度的Tsallis全息暗能量（THDE）模型。在紧凑型kaluza-klein重力框架内，提出了与广义的Chaplygin气体（GCG）相互作用的相互作用模型。结果表明，可以在当前时期找到稳定的配置，该配置也与观察到的密度参数的值兼容。值得注意的是，黑暗能（DE）可能是从幻影阶段演变而来的。发现暗能的性质取决于相互作用的耦合参数。还发现经典稳定性考虑对模型参数放置了上限。
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.
