全息熵产生的普适性

Universality in holographic entropy production

Ville Keranen, Hiromichi Nishimura, Stefan Stricker, Olli Taanila, Aleksi Vuorinen

摘要:

在一个与薄平壳引力坍缩对偶的全息热化模型中,我们考虑了两个类熵量的时间演化,即全息纠缠熵和因果全息信息。与早期的计算有效的不同的限制,我们进行了全面的治疗系统的动力学,改变壳的状态方程和初始位置。在所有的情况下,我们发现,在早期的加速壳和后期的饱和对热极限之间,纠缠熵表现出普遍的线性增长的时间按照刘和苏的预测。作为我们分析的中间步骤,我们明确地构建了一个坐标系连续的位置上的一个无限薄的壳,并推导出匹配的条件测地线和极值表面穿过这个区域。

英文摘要:

We consider the time evolution of two entropy-like quantities, the holographic entanglement entropy and causal holographic information, in a model of holographic thermalization dual to the gravitational collapse of a thin planar shell. Unlike earlier calculations valid in different limits, we perform a full treatment of the dynamics of the system, varying both the shell's equation of state and initial position. In all cases considered, we find that between an early period related to the acceleration of the shell and a late epoch of saturation towards the thermal limit, the entanglement entropy exhibits universal linear growth in time in accordance with the prediction of Liu and Suh. As intermediate steps of our analysis, we explicitly construct a coordinate system continuous at the location of an infinitely thin shell and derive matching conditions for geodesics and extremal surfaces traversing this region.
