具有次指数衰减相互作用的连续多粒子Anderson模型本征函数的指数衰减

Exponential decay of eigenfunctions in a continuous multi-particle Anderson model with sub-exponentially decaying interaction

Victor Chulaevsky

摘要:

本文是对文献[2]的补充,在文献[2]中,我们建立了一类具有合金型随机势和无限程次指数衰减相互作用的多粒子Anderson模型的强动力学局部化.我们表明,在低能量的本地化本征函数实际上是指数衰减快。这改进了Fauser和Warzel的结果,他们在存在次指数衰减相互作用的情况下建立了本征函数的次指数衰减。

英文摘要:

This short note is a complement to our recent paper [2] where we established strong dynamical localization for a class of multi-particle Anderson models in a Euclidean space with an alloy-type random potential and a sub-exponentially decaying interaction of infinite range. We show that the localized eigenfunctions at low energies actually decay exponentially fast. This improves the results by Fauser and Warzel who established sub-exponential decay of eigenfunctions in presence of a sub-exponentially decaying interaction.
