黑洞热力学中涡旋/反涡旋对的产生
Vortex/anti-vortex pair creation in black hole thermodynamics
摘要:
孤立临界点是指当Lovelock耦合常数为特殊值时,高维K阶Lovelock引力双曲黑洞相图中出现的一个特殊的热力学临界点.它对应于两个燕尾的“合并”,其特征在于非标准临界指数。在采用最近的建议分配的拓扑电荷的热力学临界点,我们认为,孤立的临界点提供了一个解释对应的发病的拓扑相变的“涡/反涡对”。
英文摘要:
An isolated critical point is a peculiar thermodynamic critical point that occurs in the phase diagram of hyperbolic black holes in Kth-order Lovelock gravity in higher dimensions (with K odd) for special tuned Lovelock coupling constants. It corresponds to a "merger" of two swallowtails and is characterized by non-standard critical exponents. Upon employing a recent proposal for assigning a topological charge to thermodynamic critical points, we argue that the isolated critical point offers an interpretation corresponding to the onset of a topological phase transition of a "vortex/anti-vortex pair".
