论文摘要
研究了在有限温度和重子密度下的$ q \ bar q $系统全息二的混乱发作。我们考虑了Black-Hole Horizon附近的$ ADS $ REISSNER-NORDSTROM背景中的一根字符串,并研究了静态配置的小时间依赖性扰动。与地平线的接近性会导致混乱,从而软化增加了化学势。还检查了包括DILATON的效果的背景几何形状。 Maldacena,Shenker和Stanford在Lyapunov的指数上绑定了表征有限的BARYON化学潜力的扰动指数,以及dilaton包括在公制中时。
Onset of chaos for the holographic dual of a $Q \bar Q$ system at finite temperature and baryon density is studied. We consider a string in the $AdS$ Reissner-Nordstrom background near the black-hole horizon, and investigate small time-dependent perturbations of the static configurations. The proximity to the horizon induces chaos, which is softened increasing the chemical potential. A background geometry including the effect of a dilaton is also examined. The Maldacena, Shenker and Stanford bound on the Lyapunov exponents characterizing the perturbations is satisfied for finite baryon chemical potential and when the dilaton is included in the metric.
