全息超导体的内部结构和复杂度增长率的M理论研究

Interior Structure and Complexity Growth Rate of Holographic Superconductor from M-Theory

Yu-Sen An, Li Li, Fu-Guo Yang, Run-Qiu Yang

摘要:

本文从M理论出发,研究了自上而下全息超导体的内部动力学。带电标量头发的凝聚必然会移除内部柯西视界,时空终止于类空奇点。虽然在临界温度有一个平滑的超导相变,但超导性的开始伴随着复杂的内部动力学,包括爱因斯坦-罗森桥的坍塌,凝聚态的约瑟夫森振荡和最后的卡斯纳奇点。我们解析地得到了不同Kasner历元交替的变换规律。由于自上而下理论的非线性耦合,卡斯纳时代通常会朝着奇点进行永无休止的混乱交替。我们计算全息复杂性使用的复杂性作用和复杂性体积对偶。与后者相反,复杂性-作用二重性的复杂性增长率在临界温度具有不连续性,表征了超导相变前后内部结构的突变。

英文摘要:

We study the interior dynamics of a top-down holographic superconductor from M-theory. The condense of the charged scalar hair necessarily removes the inner Cauchy horizon and the spacetime ends at a spacelike singularity. Although there is a smooth superconducting phase transition at the critical temperature, the onset of superconductivity is accompanied by intricate interior dynamics, including the collapse of the Einstein-Rosen bridge, the Josephson oscillations of the condensate, and the final Kasner singularity. We obtain analytically the transformation rule for the alternation of different Kasner epochs. Thanks to the nonlinear couplings of the top-down theory, there is generically a never-ending chaotic alternation of Kasner epochs towards the singularity. We compute the holographic complexity using both the complexity-action and the complexity-volume dualities. In contrast to the latter, the complexity growth rate from the complexity-action duality has a discontinuity at the critical temperature, characterizing the sudden change of the internal structure before and after the superconducting phase transition.
