摘要:

在本文中,我们数值构造新的带电反德西特黑洞耦合到非线性玻恩-因菲尔德电动力学在一定的类标量张量理论。的解决方案的性质进行了研究,数值和分析。我们还研究了正则系综中黑洞的热力学性质。对于较大的Born-Infeld参数值和一定的电荷值区间,我们发现存在一个一级相变之间的小和非常大的黑洞。一个意想不到的结果是,对于某个小的电荷子区间,观察到两个相变,一个是零阶相变,一个是一阶相变。值得注意的是,纯爱因斯坦-玻恩-因菲尔德-AdS黑洞也观察到了这样的相变。

英文摘要:

In the present paper we numerically construct new charged anti-de Sitter black holes coupled to nonlinear Born-Infeld electrodynamics within a certain class of scalar-tensor theories. The properties of the solutions are investigated both numerically and analytically. We also study the thermodynamics of the black holes in the canonical ensemble. For large values of the Born-Infeld parameter and for a certain interval of the charge values we find the existence of a first-order phase transition between small and very large black holes. An unexpected result is that for a certain small charge subinterval two phase transitions have been observed, one of zeroth and one of first order. It is important to note that such phase transitions are also observed for pure Einstein-Born-Infeld-AdS black holes.
