Dynamical Topological Phase Transition in Massless Thirring Model
Hiroshi Nohara
Abstract
We study the topological nature of both isotropic and anisotropic SU(N) Thirring model. It is shown that in the isotropic model there exists the special point where the system lives in the topological phase and that in the anisotropic one which is obtained by introducing two coupling constants and has U(1) symmetry, we present a simple mechanism of the dynamical topological phase transition which takes place at the infinite energy scale.
