高温时空非对易U(1)模型

On space-time noncommutative U(1) model at high temperature

Alexei Strelchenko

摘要:

本文将文献[arXiv:0705.4294]的结果推广到有限温度下的非对易规范理论。特别地,利用背景场方法,我们在虚时形式下分析了非对易U(1)规范模型的重整化问题和单圈欧氏自由能的高温渐近性.作为副产品,研究了任意背景规范下非对易$S^1 \times R^3$流形上非最小光子动力学算符的热迹。考虑了$S^1 \times R^3$上所有可能的非对易性。结果表明,在高温下,模型的非平面部分对系统的自由能没有贡献。对所得结果进行了讨论。

英文摘要:

We extend the results of Ref. [arXiv:0705.4294] to noncommutative gauge theories at finite temperature. In particular, by making use of the background field method, we analyze 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 $S^1 \times R^3$ manifold taken in an arbitrary background gauge is investigated. All possible types of noncommutativity on $S^1 \times R^3$ 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.
