Unstable Modes in Three-Dimensional SU(2) Gauge Theory
arXiv:hep-lat/9303003 · doi:10.1103/PhysRevD.48.3364
Abstract
We investigate SU(2) gauge theory in a constant chromomagnetic field in three dimensions both in the continuum and on the lattice. Using a variational method to stabilize the unstable modes, we evaluate the vacuum energy density in the one-loop approximation. We compare our theoretical results with the outcomes of the numerical simulations.
