临界态的Bekenstein-Hawking熵

Bekenstein-Hawking entropy from Criticality

Swastik Bhattacharya, S. Shankaranarayanan

摘要:

真空爱因斯坦方程在投射到黑洞视界时类似于流体动力学。在这项工作中,我们解决的问题,半经典黑洞的某些属性是否可以全息映射到(2 + 1)维流体生活在地平线上的属性。特别是,我们专注于统计力学描述的水平流体,导致贝肯斯坦-霍金熵。在朗道平均场论的范式和存在的凝聚在临界温度,我们明确表明,贝肯斯坦-霍金熵和其他功能的黑洞热力学可以恢复从统计建模的流体。我们还表明,一个负的宇宙学常数的行为就像一个外部的磁场,诱导系统中的秩序,导致出现在相图中的三临界点。

英文摘要:

Vacuum Einstein equations when projected on to a black hole horizon is analogous to the dynamics of fluids. In this work we address the question, whether certain properties of semi-classical black holes could be holographically mapped into properties of (2 + 1)-dimensional fluid living on the horizon. In particular, we focus on the statistical mechanical description of the horizon-fluid that leads to Bekenstein-Hawking entropy. Within the paradigm of Landau mean field theory and existence of a condensate at a critical temperature, we explicitly show that Bekenstein-Hawking entropy and other features of black hole thermodynamics can be recovered from the statistical modelling of the fluid. We also show that a negative cosmological constant acts like an external magnetic field that induces order in the system leading to the appearance of a tri-critical point in the phase diagram.
