标题： Lifshitz black holes in string theory

摘要： 我们提供了在弦理论中找到的第一个具有Lifshitz渐近性的黑洞解。 这些解预期与在有限温度下具有各向异性尺度不变性的模型相对应，动力指数z=2。 我们采用了一种一致的截断类型IIB超引力至四维，其中内部几何为任意五维爱因斯坦流形乘以一个圆。 发现了新的有趣特性，这些特性与现象学模型中的先前结果有显著不同。 特别是，小黑洞被证明在热力学上是不稳定的，类似于通常的AdS-Schwarzschild黑洞，并且无法达到极端性。 这表明在低温下可能存在类似Hawking-Page的相变。 显示英文摘要

摘要： We provide the first black hole solutions with Lifshitz asymptotics found in string theory. These are expected to be dual to models enjoying anisotropic scale invariance with dynamical exponent z=2 at finite temperature. We employ a consistent truncation of type IIB supergravity to four dimensions with an arbitrary 5-dimensional Einstein manifold times a circle as internal geometry. New interesting features are found that significantly differ from previous results in phenomenological models. In particular, small black holes are shown to be thermodynamically unstable, analogously to the usual AdS-Schwarzschild black holes, and extremality is never reached. This signals a possible Hawking-Page like phase transition at low temperatures.
