玻色多体模型的小场抛物流:第四部分:背景场和临界场的估计

The Small Field Parabolic Flow for Bosonic Many-body Models: Part 4 - Background and Critical Field Estimates

Tadeusz Balaban, Joel Feldman, Horst Knörrer, Eugene Trubowitz

摘要:

本文是对三维格点上弱相互作用多玻色子系统在低温下对称性破缺程序的贡献。这是一个分析的“小场”近似的“抛物线流”,表现出形成一个“墨西哥帽”的势阱。在这里,我们证明了背景和临界场的存在性和界限,所产生的最陡下降攻击,这是在我们的重整化群步骤分析这些模型的核心。

英文摘要:

This paper is a contribution to a program to see symmetry breaking in a weakly interacting many Boson system on a three dimensional lattice at low temperature. It is part of an analysis of the "small field" approximation to the "parabolic flow" which exhibits the formation of a "Mexican hat" potential well. Here we prove the existence of and bounds on the background and critical fields that arise from the steepest descent attack that is at the core of our renormalization group step anaylsis of these models.
