Lorentz破缺引力的Smarr公式的改进推导

An improved derivation of the Smarr Formula for Lorentz-breaking gravity

Costantino Pacilio, Stefano Liberati

摘要:

在过去的几年里,由于宇宙视界的存在,在引力理论中没有局部洛伦兹不变性的黑洞的热力学性质一直受到激烈的研究,这是强大的因果障碍,即使是超光速信号。在这里,我们提出了一种新的一般方法来推导这类理论的Smarr公式:特别是我们表明,爱因斯坦-以太理论和红外Horava引力的Smarr公式遵循标度不变性。我们不仅直接再现以前的静态黑洞解的结果,但我们也能够将它们推广到静止旋转黑洞的情况。最后,我们将所得结果应用于三维旋转的具有普适视界的黑洞,从中我们将得到一些关于具有普适视界的黑洞解的黑洞热力学可行性的经验.

英文摘要:

Thermodynamical properties of black holes in gravitational theories without Local Lorentz invariance have been subject to intense investigation in the past years due to the presence of universal horizons, which are strong causal barriers even for superluminal signals. Here we present a novel general method for deriving the Smarr formula for this class of theories: in particular we show that the Smarr formulae for Einstein-Aether theory and infrared Horava gravity follow from scale invariance. We not only reproduce straightforwardly previous findings for static black hole solutions, but we are also able to generalise them to the case of stationary rotating black holes. Finally, we apply our results to the rotating black holes with universal horizon as found in three dimensions, from which we shall draw some lessons on the viability of black hole thermodynamics for black hole solutions endowed with universal horizons.
