随机磁场的Wegner估计和安德森局域化

Wegner estimate and Anderson localization for random magnetic fields

Laszlo Erdoes, David Hasler

摘要:

本文考虑一个具有空间平稳随机磁场的二维磁薛定谔算子。我们假设磁场有一个正的下限,它具有任意短尺度上的傅立叶模式。我们证明了在任意能量下的Wegner估计,即我们证明了在整个谱中的平均态密度是有限的。我们还证明了安德森局域化在底部的频谱。

英文摘要:

We consider a two dimensional magnetic Schroedinger operator with a spatially stationary random magnetic field. We assume that the magnetic field has a positive lower bound and that it has Fourier modes on arbitrarily short scales. We prove the Wegner estimate at arbitrary energy, i.e. we show that the averaged density of states is finite throughout the whole spectrum. We also prove Anderson localization at the bottom of the spectrum.
