Analysis
This paper investigates the real-time dynamics of a U(1) quantum link model using a Rydberg atom array. It explores the interplay between quantum criticality and ergodicity breaking, finding a tunable regime of ergodicity breaking due to quantum many-body scars, even at the equilibrium phase transition point. The study provides insights into non-thermal dynamics in lattice gauge theories and highlights the potential of Rydberg atom arrays for this type of research.
