Abstract Using Seibergs definition for the geometric charge in SU(2) lattice gauge theory, we have managed to apply it also to the Chern-Simons term. We checked the periodic structure and determined the Chern-Simons density on small lattices L 4 and L 3 × 2,4 with L = 4, 6, and 8 near the critcal region in the SU(2) Higgs mode. The data indicate that tunneling is increased at high temperature.

AbstractNon-Abelian gauge fields on a four-dimensional hypercubic lattice with small action density [Tr{U( $$\dot p$$ )} for SU(2) gauge fields] are shown to carry an integer topological chargeQ,Expand
Analytic study of θ vacua on the lattice
Abstract A new definition of the topological charge density for four-dimensional lattice gauge theory is given. Using a systematic expansion we find a cusp in the vacuum energy at θ = π signaling theExpand
Symmetry Breaking Through Bell-Jackiw Anomalies
In models of fermions coupled to gauge fields certain current-conservation laws are violated by Bell-Jackiw anomalies. In perturbation theory the total charge corresponding to such currents seems toExpand
