热QCD等离子体中软费米子激发的涨落耗散定理
On the fluctuation-dissipation theorem for soft fermionic excitations in a hot QCD plasma
摘要：
讨论了在处于热平衡的热非阿贝尔等离子体中软费米子激发的涨落耗散定理的两种推导方法。第一种是基于[Yu.A.]提出的描述夸克-胶子等离子体的扩展（伪）经典模型。马可夫，文学硕士Markova，Nucl.Phys.A { \bf 784}（2007）443]，而第二个依赖于计算热力学平衡系统的FDT的标准技术。我们表明，充分考虑所有的微妙之处，是共同的费米子系统正在考虑中，从而获得FDTs的完美重合的结果。这为所提出的伪经典模型的有效性提供了一个相当有力的论据。
英文摘要：
We discuss two ways of deriving the fluctuation-dissipation theorem (FDT) for soft fermion excitations in a hot non-Abelian plasma being in a thermal equilibrium. The first of them is based on the extended (pseudo)classical model in describing a quark-gluon plasma suggested in [Yu.A. Markov, M.A. Markova, Nucl. Phys. A {\bf 784} (2007) 443], while the second one rests on the standard technique of calculation of the FDT for thermodynamically equilibrium systems. We show that full accounting all subtleties that are common to the fermion system under consideration, results in perfect coincidence of thus obtained FDTs. This provides a rather strong argument for the validity of the pseudoclassical model suggested.
