Spectral diffusion and scaling of many-body delocalization transitions
arXiv:1611.02681 · doi:10.1002/andp.201600360
Abstract
We analyze the role of spectral diffusion in the problem of many-body delocalization in quantum dots and in extended systems. The spectral diffusion parametrically enhances delocalization, modifying the scaling of the delocalization threshold with the interaction coupling constant.
