Statistical localization: from strong fragmentation to strong edge modes
Tibor Rakovszky, Pablo Sala, Ruben Verresen +2
Certain disorder-free Hamiltonians can be non-ergodic due to a \emph{strong fragmentation} of the Hilbert space into disconnected sectors. Here, we characterize such systems by int…

Dynamics of strongly interacting systems: From Fock-space fragmentation to Many-Body Localization
Giuseppe De Tomasi, Daniel Hetterich, Pablo Sala +1
We study the disordered spinless fermionic chain in the strong coupling regime, . Strong interactions highly hinder the dynamics of the model, fragmenting…

Ergodicity-breaking arising from Hilbert space fragmentation in dipole-conserving Hamiltonians
Pablo Sala, Tibor Rakovszky, Ruben Verresen +2
We show that the combination of charge and dipole conservation---characteristic of fracton systems---leads to an extensive fragmentation of the Hilbert space, which in turn can lea…
