具有普适视界的渐近Lifshitz时空的能量-熵关系

Energy-entropy relation for asymptotically Lifshitz spacetimes with universal horizons

Jonathan Cheyne, David Mattingly

摘要:

在Horava-Lifshitz引力中,数值求解了动力学指数为$z=2$ ~ $z=8$的2+1渐近Lifshitz万有视界解.我们发现,对所有的$z$,存在一个热力学第一定律和Smarr公式.此外,我们发现在二维Lifshitz场论,$E=\frac{2}{z+2}TS$,热态所期望的能量-熵关系,也满足普遍的视野,包括正确的$z$标度。

英文摘要:

We numerically solve for 2+1 asymptotically Lifshitz universal horizon solutions in Horava-Lifshitz gravity for dynamical exponents $z=2$ through $z=8$. We find that for all $z$ there is a thermodynamical first law and Smarr formula. Furthermore, we find that the energy-entropy relation expected for a thermal state in a two dimensional Lifshitz field theory, $E=\frac{2}{z+2}TS$, is also satisfied for universal horizons, including the correct $z$ scaling.
