考虑非马尔可夫效应的Hawking-Page相变动力学

Kinetics of Hawking-Page phase transition with the non-Markovian effects

Ran Li, Jin Wang

摘要:

基于Hawking-Page相变的自由能景观描述,认为在热涨落作用下,从Schwarzschild-anti-de Sitter黑洞到热反de Sitter空间的相变过程是随机的.如果有效热浴的关联时间与自由能面上势阱中时空态的振荡时间相当甚至更长,则需要用黑洞相变的非马尔可夫模型来研究相变过程的动力学。非马尔可夫或记忆效应表示的时间依赖性的摩擦内核和动力学,然后由广义Langevin方程补充的自由能潜力。作为具体例子,我们研究了指数衰减摩擦核和振荡摩擦核对Hawking-Page相变动力学的影响。对于指数衰减摩擦,非马尔可夫效应促进了过渡过程;对于振荡摩擦,增大振荡频率也加快了过渡过程。

英文摘要:

Based on the free energy landscape description of Hawking-Page phase transition, the transition process from the Schwarzschild-anti-de Sitter black hole to the thermal anti-de Sitter space are considered to be stochastic under the thermal fluctuations. If the correlation time of the effective thermal bath is comparable or even longer than the oscillating time of the spacetime state in the potential well on the free energy landscape, the non-Markovian model of the black hole phase transition is required to study the kinetics of the transition processes. The non-Markovian or memory effect is represented by the time dependent friction kernel and the kinetics is then governed by the generalized Langevin equation complemented by the free energy potential. As the concrete examples, we study the effects of the exponentially decay friction kernel and the oscillatory friction kernel on the kinetics of Hawking-Page phase transition. For the exponentially decayed friction, the non-Markovian effects promote the transition process, and for the oscillatory friction, increasing the oscillating frequency also speeds up the transition process.
