Fragmentation-induced localization and boundary charges in dimensions two and above
Julius Lehmann, Pablo Sala, Frank Pollmann +1
We study higher dimensional models with symmetric correlated hoppings, which generalize a one-dimensional model introduced in the context of dipole-conserving dynamics. We prove ri…

Dynamics in Systems with Modulated Symmetries
Pablo Sala, Julius Lehmann, Tibor Rakovszky +1
We extend the notions of multipole and subsystem symmetries to more general {\it spatially modulated} symmetries. We uncover two instances with exponential and (quasi)-periodic mod…
