Prominent quantum many-body scars in a truncated Schwinger model

Abstract

Quantum many-body scars (QMBSs) are a paradigm of weak ergodicity breaking with direct technological applications. The authors show that QMBSs are ubiquitous in quantum link formulations of gauge theories, opening the door to a large venue of models where QMBSs can be explored. They demonstrate that QMBSs are not an artifact of these quantum link formulations, rather, they may be an inherent feature of the ideal gauge theory itself.
