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.

高维宇宙学中相互作用的 Tsallis 全息暗能量

我们讨论了更高维度的 Tsallis 全息暗能量 (THDE) 模型。在致密 Kaluza-Klein 引力的框架下,提出了一种与广义 Chaplygin Gas (GCG) 相互作用的暗能量模型。结果表明,在当前时期可以找到一个稳定的配置,这也与密度参数的观测值兼容。值得注意的是,暗能量 (DE) 可能是从过去的幻象阶段演变而来的。发现暗能量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设置了上限。
