矢量和轴向规范场的量子动力学理论

Quantum Kinetic Theory with Vector and Axial Gauge Fields

Zhou Chen, Shu Lin

摘要:

本文将轴向规范场引入到无质量极限下的矢量规范场量子动力学理论的框架中。将轴向规范场与矢量规范场同等对待,构造了动力学方程的一阶梯度展开或等价的半经典展开的相容解.在这项工作中提出的量子动力学理论的直观扩展提供了一个自然的推广,并产生了协变异常和协变电流。通过将Chern-Simons电流相加,可以从协变电流得到相应的一致电流。利用一致流计算了流与能量动量张量在平衡态下的各种关联函数。

英文摘要:

In this paper we introduce the axial gauge field to the framework of the quantum kinetic theory with vector gauge field in the massless limit. Treating axial-gauge field on an equal footing with the vector-gauge field, we construct a consistent solution to the kinetic equations up to the first order in gradient expansion or equivalently the semi-classical expansion. The intuitive extension of quantum kinetic theory presented in this work provides a natural generalization, and turns out to give rise to the covariant anomaly and the covariant currents. The corresponding consistent currents can be obtained from the covariant ones by adding the Chern-Simons current. We use the consistent currents to calculate various correlation functions among currents and energy-momentum tensor in equilibrium state.
