Chaotic nature of holographic QCD

In this paper, we bring together two topics in the holographic correspondence-quantum chaos and quark-gluon plasma (QGP). We establish that the first relativistic correction to drag force experienced by a charge carrier moving through a thermal medium (for example, a quark in QGP) at a constant velocity is fixed by the butterfly velocity. Moreover, we show that this result is robust against stringy corrections and anisotropy. For the jet quenching parameter, we find that it is related to the butterfly velocity along the momentum broadening direction and temperature. This opens a way to the reconstruction of butterfly velocity of quark-gluon plasma and other strongly coupled systems experimentally from rather simple observables.

Automated summary

This paper combines quantum chaos and quark-gluon plasma in holographic correspondence. It establishes a relationship between the drag force experienced by a charge carrier moving through a thermal medium and the butterfly velocity. The study suggests that the butterfly velocity can be experimentally reconstructed from simple observables in systems like quark-gluon plasma.
