黑洞贝瑞相

Black Hole Berry Phase

Jan de Boer, Kyriakos Papadodimas, Erik Verlinde

摘要:

超对称黑洞的特征是具有大量的简并基态。我们认为,这些黑洞,像其他量子力学系统与这样的简并,是受一种现象,这是所谓的几何或Berry的阶段:在绝热变化的背景值的超引力模量,量子微观状态的黑洞之间的混合。我们提出了一个简单的例子,这种混合是完全可计算的,在5维的小超对称黑洞。虽然在实践中测量黑洞的Berry相位是非常困难的,但从理论的角度进一步探索它可能是有趣的,因为它为我们提供了一种探测并在某种程度上操纵黑洞量子微观态的方法。

英文摘要:

Supersymmetric black holes are characterized by a large number of degenerate ground states. We argue that these black holes, like other quantum mechanical systems with such a degeneracy, are subject to a phenomenon which is called the geometric or Berry's phase: under adiabatic variations of the background values of the supergravity moduli, the quantum microstates of the black hole mix among themselves. We present a simple example where this mixing is exactly computable, that of small supersymmetric black holes in 5 dimensions. While in practice it would be extremely difficult to measure Berry's phase for black holes, it may be interesting to explore it further from a theoretical point of view, as it provides us with a way to probe, and to some degree manipulate, the quantum microstate of the black hole.
