Fractal non-Fermi liquids from moiré-Hofstadter phonons
Ajesh Kumar, Zihan Cheng, Andrew C. Potter
We theoretically explore 2d moiré heterostructures in lattice-commensurate magnetic fields as platforms for quantum simulation of a paradigmatic model of non-Fermi liquid physics:…

Symmetry enforced fractonicity and quantum crystal melting
Ajesh Kumar, Andrew C. Potter
Fractons are particles that cannot move in one or more directions without paying energy proportional to their displacement. Here, we introduce the concept of symmetry enforced frac…
