Chaos in a \(Q \bar Q\) system at finite temperature and baryon density

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 pr...

Summary: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.
