Minimal Hubbard models of maximal Hilbert space fragmentation
Yves H. Kwan, Patrick H. Wilhelm, Sounak Biswas +1
We show that Hubbard models with nearest-neighbor hopping and a nearest-neighbor hardcore constraint exhibit `maximal' Hilbert space fragmentation in many lattices of arbitrary dim…

Beyond the Freshman's Dream: Classical fractal spin liquids from matrix cellular automata in three-dimensional lattice models
Sounak Biswas, Yves H. Kwan, S. A. Parameswaran
We construct models hosting classical fractal spin liquids on two realistic three-dimensional (3D) lattices of corner-sharing triangles: trillium and hyperhyperkagome (HHK). Both m…
