连续空间中两粒子Anderson模型的Wegner型界

Wegner-type bounds for a two-particle Anderson model in a continuous space

A. Boutet de Monvel, V. Chulaevsky, Y. Suhov

摘要:

我们分析了$\R^d$中具有相互作用的两粒子量子系统,以及存在具有连续自变量的随机外势场(连续空间中的Anderson模型)。我们的目标是建立这样一个模型的所谓韦格纳型估计,评估概率随机谱的哈密顿量在有限的体积与给定的集合相交。对于两粒子模型的格点形式,在[8]中得到了类似的结果

英文摘要:

We analyse a two-particle quantum system in $\R^d$ with interaction and in presence of a random external potential field with a continuous argument (an Anderson model in a continuous space). Our aim is to establish the so-called Wegner-type estimates for such a model, assessing the probability that random spectra of Hamiltonians in finite volumes intersect with a given set. For the lattice version of the two-particle model, a similar result was obtained in [8]
