有质量费米子输运理论的无质量极限

Massless Limit of Transport Theory for Massive Fermions

Xingyu Guo

摘要:

研究了大质量费米子Wigner函数不同分量的$m=0$极限。与手征动力学理论相比较,我们分离了矢量和轴向矢量的消失部分和非消失部分,直到$\hbar$的一级。然后讨论了消失部分和非消失部分的可能物理意义,以及它们在热平衡时的不同行为。

英文摘要:

We studied the $m=0$ limit of different components of Wigner functions for massive fermions. Comparing with the chiral kinetic theory, we separated the vanishing part and non-vanishing part for vector and axial vector components, up to the first order of $\hbar$. Then we discussed the possible physical meaning of the vanishing and non-vanishing parts, and their different behavior at thermal equilibrium.
