非阿贝尔等离子体的手征朗之万理论

Chiral Langevin theory for non-Abelian plasmas

Yukinao Akamatsu, Naoki Yamamoto

摘要:

具有手性不平衡的带电等离子体是不稳定的,并且倾向于减少不平衡。这种手性等离子体的不稳定性,但是,不捕获(异常)流体力学高温非阿贝尔等离子体。我们推导了一个描述手征等离子体在磁尺度下不稳定性的具有反常宇称破坏效应的Langevin型经典有效理论。我们表明,不稳定的时间尺度是$[g^4 T \ln(1/g)]^{-1}$顺序在弱耦合。

英文摘要:

Charged plasmas with chirality imbalance are unstable and tend to reduce the imbalance. This chiral plasma instability is, however, not captured in (anomalous) hydrodynamics for high-temperature non-Abelian plasmas. We derive a Langevin-type classical effective theory with anomalous parity-violating effects for non-Abelian plasmas that describes the chiral plasma instability at the magnetic scale. We show that the time scale of the instability is of order $[g^4 T \ln(1/g)]^{-1}$ at weak coupling.
