Abstract

The Bekenstein bound, inspired by the physics of black holes, is introduced to constrain the entropy growth of a physical system down to the quantum level in the context of a generalized second law of thermodynamics. We first show that the standard Bekenstein bound is violated when the entropy of a Schwarzschild black hole is described in non-Gaussian statistics Barrow, Tsallis, and Kaniadakis due to the presence of the related indices Δ, q and κ, respectively. Then, by adding the GUP effects into the Bekenstein bound, we find that the generalized bound is satisfied in the context of the mentioned entropies through a possible connection between the entropies indices and the GUP parameter β.
非高斯统计中黑洞熵的贝肯斯坦界
贝肯斯坦界是受黑洞物理学启发,在广义热力学第二定律的背景下,将物理系统的熵增长限制在量子水平。我们首先证明,由于相关指标Δ、q和κ的存在,当非高斯统计量Barrow、Tsallis和Kaniadakis描述史瓦西黑洞的熵时,违反了标准Bekenstein界。然后,通过将GUP效应加入到Bekenstein界中,我们发现,通过熵指标与GUP参数β之间的可能联系,在上述熵的范围内,广义界是满足的。
