Holographic energy loss of a rotating heavy quark at finite chemical potential

Abstract

We study the energy lost by a rotating heavy point particle along a circle of radius l with angular velocity ω in N=4 super Yang-Mills (SYM) theory with chemical potential from holography. We compute the energy loss both from the drag force channel and radiation channel, respectively. It is shown that for both cases the inclusion of chemical potential tends to increase the energy loss, consistently with the findings of the energy loss of a linearly moving quark.
