Thermalization and Its Absence within Krylov Subspaces of a Constrained Hamiltonian
Thermalization and Its Absence within Krylov Subspaces of a Constrained Hamiltonian
We study the quantum dynamics of a simple translation invariant, center-of-mass (CoM) preserving model of interacting fermions in one dimension (1D), which arises in multiple experimentally realizable contexts. We show that this model naturally displays the phenomenology associated with fractonic systems, wherein single charges can only move by emitting dipoles. …
