Holographic Study of the $Q\bar{Q}$ Chaotic Dynamics in General Thermal Background

The holographic approach is applied to study the chaotic behaviour of a strongly coupled $Q\bar{Q}$ pair in general thermal background. We consider two different backgrounds, one with finite temperature and baryon density, and one with finite temperature and constant magnetic field along a fixed direction. The results allow us to understand the dependence of the chaotic dynamics on the background, to test the universal bound on chaos conjectured by Maldacena, Shenker and Standford (MSS)
