Topologically massive chromodynamics at finite temperature

Abstract

Topologically massive chromodynamics is studied at a finite temperature T. The topological gauge invariance present at T=0 is argued to remain valid at T\ensuremath{\ne}0, but verifying this in the quantum theory is far less direct at T\ensuremath{\ne}0 than at T=0. Debye screening occurs, and has a striking effect on the correlations of static magnetic fields. The behavior of the free energy at high temperature is also computed.
