论文摘要
等离子体球是被限制真空包围的脱糊状等离子体的液滴。我们通过五维抗DE保姆(ADS)Soliton背景中局部的有限能源黑洞的动力学对其实时演变进行了第一次全息模拟。双量规理论是四维的,n = 4个超级阳米尔在具有超对称性边界条件的圆上压实。我们考虑通过无质量标量场来提供的无水平初始数据。迅速的标量场崩溃,然后在几何形状的底部产生一个激发的黑洞,并引力辐射和标量辐射。辐射分散在非绘制方向上的无穷大,对应于双仪理论中的粒子产生。黑洞以时间尺度的比例比预期的时间更长的时间尺度朝着平衡等离子体球的双重演变。此功能是限制的直接结果,是由索利顿底部和广告边界之间长期寿命的周期性干扰引起的。
Plasma balls are droplets of deconfined plasma surrounded by a confining vacuum. We present the first holographic simulation of their real-time evolution via the dynamics of localized, finite-energy black holes in the five-dimensional anti-de Sitter (AdS) soliton background. The dual gauge theory is four-dimensional, N=4 super Yang-Mills compactified on a circle with supersymmetry-breaking boundary conditions. We consider horizonless initial data sourced by a massless scalar field. Prompt scalar field collapse then produces an excited black hole at the bottom of the geometry together with gravitational and scalar radiation. The radiation disperses to infinity in the noncompact directions and corresponds to particle production in the dual gauge theory. The black hole evolves toward the dual of an equilibrium plasma ball on a time scale longer than naively expected. This feature is a direct consequence of confinement and is caused by long-lived, periodic disturbances bouncing between the bottom of the AdS soliton and the AdS boundary.
