Abstract:

We study spin-echo signals in disordered Hubbard models. We show that the spin echo signal is characterized by a timescale which depends non-monotonically on disorder strength through the many-body localization transition. Our results yield a tool for detecting the transition which is based on short time evolution, making it efficient numerically and an attractive tool for experimental implementation.
