平面波矩阵模型中快速热化的证据

Evidence for fast thermalization in the plane-wave matrix model

Curtis T. Asplund, David Berenstein, Diego Trancanelli

摘要:

本文对具有半经典初始条件的平面波矩阵模型的经典演化进行了数值模拟。这些初始条件中的一些热化了,并且与平面波几何中D膜碰撞形成的黑洞是对偶的。特别地,我们考虑一个大的模糊球(一个D2-膜)加上一个单本征值(一个D 0-粒子)正好穿过模糊球的中心并与之相交,在初始条件下,包括非对角模的量子涨落,在足够的动能下,该构型坍缩到一个小尺寸。我们还发现了快速热化的证据:相对于系统的自然时间尺度,在后期迅速衰减的自相关函数。

英文摘要:

We perform a numerical simulation of the classical evolution of the plane-wave matrix model with semiclassical initial conditions. Some of these initial conditions thermalize and are dual to a black hole forming from the collision of D-branes in the plane wave geometry. In particular, we consider a large fuzzy sphere (a D2-brane) plus a single eigenvalue (a D0-particle) going exactly through the center of the fuzzy sphere and aimed to intersect it. Including quantum fluctuations of the off-diagonal modes in the initial conditions, with sufficient kinetic energy the configuration collapses to a small size. We also find evidence for fast thermalization: rapidly decaying autocorrelation functions at late times with respect to the natural time scale of the system.
