Abstract

In this paper we investigate the effect of repulsive pair interactions on Bose-Einstein condensation in a well-established random one-dimensional system known as the Luttinger-Sy model at positive temperature. We study separately hard core interactions as well as a class of more general repulsive interactions, also allowing for a scaling of certain interaction parameters in the thermodynamic limit. As a main result, we prove in both cases that for sufficiently strong interactions all eigenstates of the non-interacting one-particle Luttinger-Sy Hamiltonian as well as any sufficiently localized one-particle state are almost surely not macroscopically occupied.
Luttinger-Sy模型中排斥对玻色-爱因斯坦凝聚的影响
在本文中,我们研究了在正温度下被称为Luttinger-Sy模型的一个已建立的随机一维系统中,排斥对相互作用对玻色-爱因斯坦凝聚的影响。我们分别研究了硬核相互作用以及一类更一般的排斥相互作用,也允许在热力学极限下缩放某些相互作用参数。作为主要结果,我们证明了在两种情况下,对于足够强的相互作用,非相互作用的单粒子Luttinger-Sy哈密顿量的所有特征态以及任何足够局域的单粒子态几乎肯定不被宏观占据。
