Localization in a disorder-free model after a global quantum quench. — •Adam Smith1, Johannes Knolle1, Dmitry Kovrizhin2, and Roderich Moessner3 — 1T.C.M. group, Cavendish Laboratory, JJ Thomson Ave, Cambridge CB3 0HE, United Kingdon — 2Rudolf Peierls Centre for Theoretical Physics, 1 Keble Road, Oxford OX1 3NP, United Kingdom — 3Max-Planck-Institut für Physik komplexer Systeme, 01187 Dresden, Germany
We consider an interacting, translation invariant one dimensional model in which we observe complete localisation in one of two fermionic subsystems. Its effective disorder is generated dynamically and can be rigorously identified through a set of conserved quantities. To corroborate the emergence of localization after a global quantum quench we show persistence of a density wave in the initial state, absence of domain-wall melting, and suppression of light-cone growth of correlations.
