stable ergodicity breaking. These results hold for both periodic and open boundary
conditions, and derive from a one-form symmetry (notably not being restricted to sectors of
extremal one-form charge). We identify simple models in which this one-form symmetry can
be emergent, giving rise to the aforementioned ergodicity breaking as an exponentially long-
lived prethermal phenomenon. We unveil a web of dualities that connects these models, in …
