非交换规范理论中的Turbulence

Turbulence in nonabelian gauge theory

J. Berges, S. Scheffler, D. Sexty

摘要:

在非交换规范理论中,Kolmogorov波湍流对等离子体不稳定性后的热化过程起着重要的作用。我们表明,SU(2)规范理论中的经典统计模拟表明了从标量模型中已知的柯尔莫戈洛夫标度指数。在图解微扰理论的有效性范围内,这一结果与解析估计一致。我们研究了经典统计与量子修正的效果,并证明了后者导致在远紫外光中没有湍流。

英文摘要:

Kolmogorov wave turbulence plays an important role for the thermalization process following plasma instabilities in nonabelian gauge theories. We show that classical-statistical simulations in SU(2) gauge theory indicate a Kolmogorov scaling exponent known from scalar models. In the range of validity of resummed perturbation theory this result is shown to agree with analytical estimates. We study the effect of classical-statistical versus quantum corrections and demonstrate that the latter lead to the absence of turbulence in the far ultraviolet.
