Gaussian approximation of the (2+1) dimensional Thirring model in the functional Schrödinger picture
arXiv:hep-th/9406070 · doi:10.1103/PhysRevD.50.6542
Abstract
The (2+1)-dimensional Thirring model is studied by using the Gaussian approximation method in the functional Schrödinger picture. Although the dynamical symmetry breaking does not occur in the large N limit, it does occur in the Gaussian approximation which includes the higher order contributions in 1/N.
