无序随机Ising模型谱的1-粒子分支的位置

On the Location of the 1-particle Branch of the Spectrum of the Disordered Stochastic Ising Model

M. Gianfelice, M. Isopi

摘要:

我们分析了较低的非平凡的一部分的谱的发电机的Glauber动力学,我们认为这是一个积极的运营商,为d-维最近邻伊辛模型与有界随机潜力。我们证明猜想1在一份文件中Albeverio等人。(称为[AMSZ]),也就是说,对于足够大的温度值,该过程的发生器的频谱的第一频带与实直线的闭合非随机段重合。

英文摘要:

We analyse the lower non trivial part of the spectrum of the generator of the Glauber dynamics, which we consider a positive operator, for a d-dimensional nearest neighbour Ising model with a bounded random potential. We prove conjecture 1 in a paper by Albeverio et al.(referred as [AMSZ]) that is, for sufficently large values of the temperature, the first band of the spectrum of the generator of the process coincides with a closed non random segment of the real line.
