树上随机薛定谔算子的Lifshitz尾扩张态
Extended States in a Lifshitz Tail Regime for Random Schrödinger Operators on Trees
摘要：
我们解决了一个现有的问题，关于移动边缘的位置与跳跃项和随机潜在的Bethe格上的运营商。该模型是最早研究安德森局域化的模型之一，并且由于与许多粒子系统的局域化问题的类比而继续引起人们的关注。我们发现，扩展状态出现通过无序使能共振远远超出运营商的跳跃项的能带。对于弱无序，这包括非常低密度的状态的Lifshits尾制度。
英文摘要：
We resolve an existing question concerning the location of the mobility edge for operators with a hopping term and a random potential on the Bethe lattice. The model has been among the earliest studied for Anderson localization, and it continues to attract attention because of analogies which have been suggested with localization issues for many particle systems. We find that extended states appear through disorder enabled resonances well beyond the energy band of the operator's hopping term. For weak disorder this includes a Lifshits tail regime of very low density of states.
