2+1维宇称奇平衡配分函数

Parity odd equilibrium partition function in 2+1 dimensions

Juan L. Mañes, Manuel Valle

摘要:

本文用Schwinger的本征时间方法计算了在静态规范和引力背景下2+1维费米子理想气体的宇称奇对U(1)流和能量动量张量的贡献。从这些结果的平衡配分函数在一阶导数展开明确获得的积分。计算的配分函数的形式与基于Kaluza-Klein和规范不变性的一般参数一致。

英文摘要:

We use Schwinger's proper time method to compute the parity odd contributions to the U(1) current and energy-momentum tensor of an ideal gas of fermions in 2+1 dimensions in the presence of static gauge and gravitational backgrounds. From these results the equilibrium partition function at first order in the derivative expansion is explicitly obtained by integration. The form of the computed partition function is consistent with general arguments based on Kaluza-Klein and gauge invariance.
