我们利用规范弦对偶性计算了重夸克运动通过N=4规范理论热态所产生的坡印亭矢量。观察到明显的扩散尾流和马赫锥。我们讨论进入声音模式的能量与来自尾流的能量之比。
We evaluate the Poynting vector generated by a heavy quark moving through a thermal state of N=4 gauge theory using the gauge-string duality. 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.
