虚时温度场论中的维数正规化及QED二圈热力学势

Dimensional Regularization in Imaginary-Time Temperature Field Theory and Thermodynamic Potential of Two-Loop QED

对在虚时温度场论的框架下进行维数正规化的步骤和方法作了一般性地讨论.作为应用的例子,计算了 QED 的双圈热力学势及其重整化.

This paper is intended to discuss generally the method and procedure of dimensi- onal regularization wihin the imaginary-time formalisim(ITF).As an example,we app it to calculate the thermodynamic potential of two-loop QED and the renormaliza- tion.
