夸克-胶子等离子体中的色动力学涨落

Chromodynamic Fluctuations in Quark-Gluon Plasma

Stanislaw Mrowczynski

摘要:

在无碰撞夸克-胶子等离子体中,色动力学场的涨落被发现作为初值线性化问题的解。等离子体初始状态是平均无色、稳定和均匀的。当状态是稳定的,初始波动指数衰减,并在长时间限制的波动建立一个平稳的频谱。对于平衡等离子体,它再现了由涨落耗散关系提供的谱。在不稳定的等离子体中,初始波动的记忆是不会丢失的波动,也进行了讨论。

英文摘要:

Fluctuations of chromodynamic fields in the collisionless quark-gluon plasma are found as a solution of the initial value linearized problem. The plasma initial state is on average colorless, stationary and homogeneous. When the state is stable, the initial fluctuations decay exponentially and in the long-time limit a stationary spectrum of fluctuations is established. For the equilibrium plasma it reproduces the spectrum which is provided by the fluctuation-dissipation relation. Fluctuations in the unstable plasma, where the memory of initial fluctuations is not lost, are also discussed.
