自对偶平面非对易理论中的单圈效应

One-loop effects in a self-dual planar noncommutative theory

C. D. Fosco, G. A. Moreno

摘要:

本文研究了具有Grosse-Wulkenhaar项的2+1维非对易复标量场理论在自对偶点的UV性质,导出了单圈有效作用量的显式表达式.我们还考虑了当势允许U(1)对称性自发破缺时,经典作用量的非平凡最小值周围的量子效应。对于这些解,我们证明了真空能量的单圈修正是经典解的振幅和耦合常数的特殊组合的函数。

英文摘要:

We study the UV properties, and derive the explicit form of the one-loop effective action, for a noncommutative complex scalar field theory in 2+1 dimensions with a Grosse-Wulkenhaar term, at the self-dual point. We also consider quantum effects around non-trivial minima of the classical action which appear when the potential allows for the spontaneous breaking of the U(1) symmetry. For those solutions, we show that the one-loop correction to the vacuum energy is a function of a special combination of the amplitude of the classical solution and the coupling constant.
