f(R)引力中的黑洞膜范式

The Black Hole Membrane Paradigm in f(R) Gravity

Saugata Chatterjee, Maulik Parikh, Sudipta Sarkar

摘要:

对于外部观察者来说,黑洞的事件视界看起来就像一个动态的流体膜。我们将这种膜范式推广到一般$f(R)$引力理论中的黑洞。我们导出了流体的应力张量和各种输运系数,发现除了爱因斯坦引力的特殊情况外,膜表现为非牛顿流体。利用欧氏方法,我们研究了膜的热力学。我们推测什么样的引力理论承认具有流体性质的视界。

英文摘要:

To an outside observer, a black hole's event horizon appears to behave exactly like a dynamical fluid membrane. We extend this membrane paradigm to black holes in general $f(R)$ theories of gravity. We derive the stress tensor and various transport coefficients of the fluid and find that the membrane behaves as a non-Newtonian fluid except for the special case of Einstein gravity. Using Euclidean methods, we study the thermodynamics of the membrane. We speculate on what theories of gravity admit horizons with fluid properties.
