Abstract
We extend the results of Strelchenko and Vassilevich (2007 Phys. Rev. D 76 065014) to noncommutative gauge theories at finite temperature. In particular, by making use of the background field method, we analyse renormalization issues and the high-temperature asymptotics of the one-loop Euclidean free energy of the noncommutative U(1) gauge model within imaginary time formalism. As a by-product, the heat trace of the non-minimal photon kinetic operator on noncommutative S1 × R3 manifold taken in an arbitrary background gauge is investigated. All possible types of noncommutativity on S1 × R3 are considered. It is demonstrated that the non-planar sector of the model does not contribute to the free energy of the system at high temperature. The obtained results are discussed.
