QED3中费米子传播子的结构

Structure of the fermion propagator in QED3

Yuichi Hoshino

摘要:

本文用类色散方法计算了QED $_{2+1}$中费米子传播子的Minkowski结构。在规范d=-1.屏蔽效应抑制了少量费米子味N时的手征序参量,我们计算了手征序参量作为耦合常数c和N的函数,存在一个临界区域,在该区域手征对称性为动态破碎

英文摘要:

Minkowski structure of the Fermion propagator in QED$_{2+1}$ is evaluated using dispersion like method Including massive fermion loop to the photon spectral function there is no infrared divergences in the gauge d=-1.Screening effects suppress the chiral order parmeter for small numbers of fermion flavour N.We evaluate the order parameter as a function of coupling constant c and N.There exsists a critical region where the chiral symmetry is dynamically broken.
