格点Anderson模型中的相关估计

Correlations Estimates in the Lattice Anderson Model

Jean V. Bellissard, Peter D. Hislop, Günter Stolz

摘要:

给出了格上随机薛定谔算子预解式的任意矩的相关估计的一个新的证明,推广和扩展了Minami的二阶矩的相关估计。我们应用这一时刻的约束,以获得一个新的$n$级韦格纳型估计,测量本征值的相关性,通过一个上界的概率,本地哈密顿至少有$n$本征值在给定的能量区间。相关性估计的另一个后果是,结果的泊松统计的能级间距和简单的本征值在强本地化制度持有广泛的一类的消隐不变,自伴,晶格运营商与衰减的非对角项和随机电位。

英文摘要:

We give a new proof of correlation estimates for arbitrary moments of the resolvent of random Schrödinger operators on the lattice that generalizes and extends the correlation estimate of Minami for the second moment. We apply this moment bound to obtain a new $n$-level Wegner-type estimate that measures eigenvalue correlations through an upper bound on the probability that a local Hamiltonian has at least $n$ eigenvalues in a given energy interval. Another consequence of the correlation estimates is that the results on the Poisson statistics of energy level spacing and the simplicity of the eigenvalues in the strong localization regime hold for a wide class of translation-invariant, selfadjoint, lattice operators with decaying off-diagonal terms and random potentials.
