An alternative approach to dynamical mass generation in QED3
arXiv:hep-th/0310093 · doi:10.1016/j.aop.2004.03.005
Abstract
Some quantum properties of QED3 are studied with the help of an exact evolution equation of the effective action with the bare fermion mass. The resulting effective theory and the occurrence of a dynamical mass are discussed in the framework of the gradient expansion.
