熵的一致流动

A consistent flow of entropy

Mohammad H Ansari

摘要:

计算量子系统熵的一种常用方法是求解主布洛赫方程来确定密度矩阵并将其代入熵的定义中。然而,这种方法最近被理解为缺乏许多能量转换器。新的熵估计器使熵估计不同于上述替代方法。这种复杂性的原因在于熵的非线性。在本文中,我们提出了一种教学方法来评估新的解释者,并解释他们的贡献的分析。我们表明,熵的内在非线性使热力学第二定律携带新的条款与新的制冷剂。我们的结果显示了重要的量子黑洞的新评论。我们的形式主义表明,在事件视界的状态简并的概念,使一个必不可少的偏离黑洞熵的领先秩序。

英文摘要:

A common approach to evaluate entropy in quantum systems is to solve a master-Bloch equation to determine density matrix and substitute it in entropy definition. However, this method has been recently understood to lack many energy correlators. The new correlators make entropy evaluation to be different from the substitution method described above. The reason for such complexity lies in the nonlinearity of entropy. In this paper we present a pedagogical approach to evaluate the new correlators and explain their contribution in the analysis. We show that the inherent nonlinearity in entropy makes the second law of thermodynamics to carry new terms associated to the new correlators. Our results show important new remarks on quantum black holes. Our formalism reveals that the notion of degeneracy of states at the event horizon makes an indispensable deviation from black hole entropy in the leading order.
