静态时空的熵力、全息和热力学

Entropic force, holography and thermodynamics for static space-times

R. A. Konoplya

摘要:

最近Verlinde提出了一种新的引力方法,将引力相互作用解释为一种熵力。新方法使用全息原理,说明信息保持在全息屏幕上,这些屏幕与等势面重合。出于这种新的解释重力(但不限于它),我们研究等势面,Unruh Verlinde温度,能量和加速度为各种静态时空:一般球对称的解决方案,轴对称黑洞沉浸在一个磁场,traversable球对称虫洞的任意形状的功能,系统的两个和两个以上的极端带电黑洞平衡。特别是,我们已经表明,Unruh-Verlinde温度的全息屏幕达到绝对零度的虫洞喉独立的特定形式的虫洞解决方案。

英文摘要:

Recently Verlinde has suggested a new approach to gravity which interprets gravitational interaction as a kind of entropic force. The new approach uses the holographic principle by stating that the information is kept on the holographic screens which coincide with equipotential surfaces. Motivated by this new interpretation of gravity (but not being limited by it) we study equipotential surfaces, the Unruh-Verlinde temperature, energy and acceleration for various static space-times: generic spherically symmetric solutions, axially symmetric black holes immersed in a magnetic field, traversable spherically symmetric wormholes of an arbitrary shape function, system of two and more extremely charged black holes in equilibrium. In particular, we have shown that the Unruh-Verlinde temperature of the holographic screen reaches absolute zero on the wormhole throat independently of the particular form of the wormhole solution.
