Topological transitions in the euclidean 2d U(1)-Higgs model

高能物理 - 格点 2009-10-28 v1

摘要

The two-dimensional U(1)-gauged Higgs model is studied on an euclidean lattice of size L1×L2L_1\times L_2, where the temperature T=L21T=L_2^{-1} is of the order of the sphaleron mass. The simulation parameters are taken from zero temperature results. By comparison with classical and semiclassical results I discuss, whether the sphaleron transition rate can be extracted from the behavior of the Chern-Simons number and from the formation of vortices in an euclidean simulation at high temperatures.
