Steven S. Gubser, Silviu S. Pufu, and Amos Yarom
TL;DR
This paper uses AdS/CFT to analyze the energy distribution and wave patterns, including diffusion wakes and Mach cones, created by a heavy quark moving in a thermal gauge theory.
Contribution
It provides a detailed calculation of the Poynting vector and energy distribution around a moving heavy quark in a thermal plasma using holographic duality.
Findings
Identification of a significant diffusion wake behind the quark
Observation of a Mach cone structure in the energy flow
Analysis of the energy ratio between sound modes and the wake
Abstract
We evaluate the Poynting vector generated by a heavy quark moving through a thermal state of N=4 gauge theory using AdS/CFT. A significant diffusion wake is observed as well as a Mach cone. We discuss the ratio of the energy going into sound modes to the energy coming in from the wake.
