We present a new route to ergodicity breaking via Hilbert space fragmentation that displays an unprecedented level of robustness, being stable to all finite orders in perturbation theory.

We present a generalized family of quantum loop models that provably exhibit topologically stable ergodicity breaking.

We outline how multidimensional coherent spectroscopy can be used to extract quantitative information about interaction effects in many-body quantum systems.

Multipole symmetries are of interest in multiple contexts, from the study of fracton phases, to nonergodic quantum dynamics, to the …
