This paper considers Tsallis holographic dark energy in an FLRW universe that is flat, with the future event horizon serving as an IR cutoff. We examine the evolutionary behavior of parameters related to dark energy density and the equation of state for different values of Tsallis exponent δ, and observe suitable behavior in the model. Here δ>1 in lower redshift region corresponds to phantom behavior of Tsallis holographic dark energy. An effort is made to reconstruct the potential of the phantom for δ>1 with lower redshift by examining the dynamics of the scalar field.

Tsallis 全息暗能量的幻影模型

本文考虑了 FLRW 宇宙中的 Tsallis 全息暗能量,该宇宙是平坦的,未来事件视界作为 IR 截止点。我们检查了与暗能量密度相关的参数的演化行为和不同 Tsallis 指数值的状态方程δ,并观察模型中的适当行为。这里δ>1个在较低的红移区域对应于 Tsallis 全息暗能量的幻影行为。努力重建幻影的潜力δ>1个通过检查标量场的动态,具有较低的红移。
