论文摘要
我们考虑了一个tsallis全息暗能模型，与深色能量与物质之间的相互作用。暗能量的密度被视为$ρ_d\ sim 3c^2/l^{4-2γ} $，其中$ c $，$γ$是常数。事件范围被选为特征量表$ l $。分析了宇宙的宇宙动力学，特别注意越过幻影线$ W_ {eff} = - 1 $。结果表明，对于某些参数值，这可能不仅发生一次，而且发生两次。
We consider a Tsallis holographic dark energy model with interaction between dark energy and matter. The density of dark energy is taken as $ρ_d \sim 3C^2/L^{4-2γ}$, where $C$, $γ$ are constants. The event horizon is chosen as the characteristic scale $L$. The cosmological dynamics of the universe are analyzed, with special attention paid to the possibility of crossing the phantom line $w_{eff}=-1$. It is shown that for certain values of parameters this may occur not only once, but also twice.
