Abstract

The Yang-Mills-aether theory is considered. Implications of the non-abelian aether-like term, which introduces violation of Lorentz symmetry, is investigated in a thermal quantum field theory. The Thermofield Dynamics formalism is used to introduce the temperature effects and spatial compactification. As a consequence, corrections due to the non-abelian aether term are calculated for the non-abelian Stefan-Boltzmann law and for the non-abelian Casimir energy and pressure at zero and finite temperature.
