Strong Hilbert space fragmentation and fractons from subsystem and higher-form symmetries
Charles Stahl, Oliver Hart, Alexey Khudorozhkov +1
We introduce a new route to Hilbert space fragmentation in high dimensions leveraging the group-word formalism. We show that taking strongly fragmented models in one dimension and…

Fractonic Fractional Quantum Hall Effect
Justin Schirmann, Peru d'Ornellas, Charles Stahl +1
In non-interacting systems, disorder can drive a trivial phase into a topological one. However little is known how to construct a fractional quantum Hall ground-state, a paradigmat…
