Characterizing many-body localization via exact disorder-averaged quantum noise
Systems with quenched disorder host fascinating dynamical phases including many-body localization. Theoretical description of such phases proves challenging since it requires disorder-averaging over many configurations, and very rare configurations may have an important effect. Here, the authors introduce a new method, based on the Feynman-Vernon influence functional, that allows one …
