摘要:

我们基于自由能景观研究了Euler-Heisenberg-AdS黑洞的一级相变。通过求解Fokker-Planck方程,我们研究了系统状态的概率分布。由于温度$T$或Euler-Heisenberg参数$a$的变化,小(大)黑洞有机会转变为大(小)黑洞。较高的(较低的)$T$对应于大(小)黑洞的较大概率。在某些条件下,可以获得共存的小黑洞和大黑洞状态。对于$0< a\leq \frac{32}{7} Q^2 $,当$a$较小时,可以获得小-大黑洞相变。对于较大的$a$,小(大)黑洞的概率将减小至零。对于较小的$a$,当初始状态为小(大)黑洞时,较高的(较低的)$T$或较小的(较大的)$a$可以获得更高的第一通过时间峰。对于$a<0$,较小的(较大的)$a$对应于大(小)黑洞的较大概率。当初始状态为小(大)黑洞时,较高的(较低的)$T$或较小的(较大的)$a$也可以获得更高的第一通过时间峰。

英文摘要:

We study the first order phase transition of Euler-Heisenberg-AdS black hole based on free energy landscape. By solving the Fokker-Planck equation, we research the probability distribution of the system states. The small (large) black hole can have the chance to switch to the large (small) black hole due to the change of the temperature $T$ or Euler-Heisenberg parameter $a$. A higher (lower) $T$ corresponds to a larger probability for a large (small) black hole. The coexistent small and large black hole states can be acquired for some conditions. For $0< a\leq \frac{32}{7} Q^2 $, the small-large black hole phase transition can be acquired with a small $a$. The probability of small (large) black holes will decrease to zero for a large $a$. For a small $a$, a higher peak of the first passage time can be acquired for higher (lower) $T$ or smaller (larger) $a$ with the initial small (large) black hole state. For $a<0$, a smaller (larger) $a$ corresponds to a larger probability for a large (small) black hole. A higher peak of the first passage time can also be obtained for higher (lower) $T$ or smaller (larger) $a$ with initial small (large) black hole state.
