Query: Breakdown of ergodicity in disordered U(1) lattice gauge theories   We show how U(1) lattice gauge theories display key signatures of ergodicity
breaking in the presence of a random charge background. Contrary to the widely
studied case of spin models, in the presence of Coulomb interactions, the
spectral properties of such lattice gauge theories are very weakly affected by
finite-volume effects. This allows to draw a sharp boundary for the ergodic
regime, and thus the breakdown of quantum chaos for sufficiently strong gauge
couplings, at the system sizes accessible via exact diagonalization. Our
conclusions are independent on the value of a background topological angle, and
are contrasted with a gauge theory with truncated Hilbert space, where instead
we observe very strong finite-volume effects akin to those observed in spin
chains.
