Dynamics of many-body localization in a translation-invariant quantum glass model

Dynamics of many-body localization in a translation-invariant quantum glass model

We study the real-time dynamics of a translationally invariant quantum spin chain, based on the East kinetically constrained glass model, in search for evidence of many-body localisation in the absence of disorder. Numerical simulations indicate a change, controlled by a coupling parameter, from a regime of fast relaxation---corresponding to thermalisation---to …
