Lifshitz拓扑黑洞

Lifshitz Topological Black Holes

R. B. Mann

摘要:

我发现一类黑洞解,(3+1)维理论重力耦合到阿贝尔规范场与负宇宙学常数,已被提出作为对偶理论的Lifshitz理论描述临界现象(2+1)维。这些黑洞都渐近于Lifshitz不动点几何,并且依赖于一个决定它们的面积(或大小)和电荷的参数。大多数的解决方案,获得数值,但也获得了一个精确的解决方案,为这个参数的特定值。大黑洞的热力学行为几乎是相同的,无论属,但小黑洞有很大的不同。屏蔽行为在对偶理论中对任何类都有体现,但对于小黑洞,屏蔽行为的临界长度依赖于类。

英文摘要:

I find a class of black hole solutions to a (3+1) dimensional theory gravity coupled to abelian gauge fields with negative cosmological constant that has been proposed as the dual theory to a Lifshitz theory describing critical phenomena in (2+1) dimensions. These black holes are all asymptotic to a Lifshitz fixed point geometry and depend on a single parameter that determines both their area (or size) and their charge. Most of the solutions are obtained numerically, but an exact solution is also obtained for a particular value of this parameter. The thermodynamic behaviour of large black holes is almost the same regardless of genus, but differs considerably for small black holes. Screening behaviour is exhibited in the dual theory for any genus, but the critical length at which it sets in is genus-dependent for small black holes.
