摘要: 在Einstein引力与非线性电动力学耦合的理论中,会出现一类双视界的黑洞解,称为非线性电动力学黑洞.针对这种理论,从一般形式的作用量和球对称度规出发,计算了带电黑洞的电势以及Wheeler-DeWitt片的作用量,证明了该作用量等于内外视界上的电势差与电荷的乘积.采用Susskind等人最近提出的复杂度/作用量对偶猜想,该作用量可以解释为Anti-de Sitter边界上的量子态的计算复杂度.在Reissner-Nordstrom黑洞和Born-Infeld黑洞两种特殊情况下,利用本文得到的一般结果与文献中已有的结果完全符合.

Abstract: Black holes usually have two horizons in nonlinear electrodynamics based on the Einstein gravity theory. Starting with the action and a spherical metric of general forms in this theory, we calculated the electric potential of the black hole as well as the action of the Wheeler-DeWitt patch. The action turned out to be equal to the electric charge multiplied by the potential difference between the inner and outer horizons. Following the conjecture of complexity-action duality proposed recently by Susskind et al., the action can be interpreted as the computational complexity of the quantum states on the Anti-de Sitter boundary. In the special cases of the Reissner-Nordstrom black hole and the Born-Infeld black hole, our general results agree well with the results published in the literature.

Key words: gauge/gravity duality, black hole, nonlinear electrodynamics
