对于量子海森堡铁磁体,道对相变的证明

For the Quantum Heisenberg Ferromagnet, Tao to the Proof of a Phase Transition

Paul Federbush

摘要:

我们提出的3-d相变,我们希望进行证明的大纲。同时,本文提供了一些物理理解的相变,在味道相对简单的论点,从一个本科课程。一些方向的数学研究,有趣的是在自己的权利,将建议的发展方面。我们希望并相信读者会被这条小路的自然和美丽所吸引;有些人甚至可能是狩猎老手,嗅着猎物,准备加入狩猎。中心结构将迹线Tr(exp(-beta*H))视为聚合物的格子气,每个都代表置换群中的一个循环,具有硬核相互作用。聚合物的活性有表达式所产生的主要猜想的文件。该估计导致3-d中的相变,而不是2-d。这是通过相同的论点发生的,即2-d中的随机游走具有一定的原点返回,但对于3-d中的随机游走则不然。

英文摘要:

We present the outline of a proof for the 3-d phase transition which we hope to carry forth. At the same time this paper provides some physical understanding of the phase transition, in the flavor of relatively simple arguments from an undergraduate course. A number of directions for mathematical research, interesting in their own right, will be suggested by aspects of the development. We hope and believe that readers will be enticed by the naturalness and beauty of the path; some perhaps even, big game veterans, sniffing the quarry, will be ready to join the hunt. The central construct views the trace, Tr(exp(-beta*H)), as a lattice gas of polymers, each representing a cycle in the permutation group, with hard core interactions. The activities of the polymers have expressions as arising from the main conjecture of the paper. The estimates lead to a phase transition in 3-d, but not 2-d. This occurs via the same argument that a random walk in 2-d has certain return to the origin, but not so for a random walk in 3-d.
