Robust Flat Bands with Tunable Energies in Honeycomb Superlattices
Zihao Qi, Eric Bobrow, Yi Li
Flat bands in lattice models have provided useful platforms for studying strong correlation and topological physics. Recently, honeycomb superlattices have been shown to host flat…

Monopole Charge Density Wave States in Weyl Semimetals
Eric Bobrow, Canon Sun, Yi Li
We study a new class of topological charge density wave states exhibiting monopole harmonic symmetries. The density-wave ordering is equivalent to pairing in the particle-hole chan…

Exact Results on Itinerant Ferromagnetism and the 15-puzzle Problem
Eric Bobrow, Keaton Stubis, Yi Li
We apply a result from graph theory to prove exact results about itinerant ferromagnetism. Nagaoka's theorem of ferromagnetism is extended to all non-separable graphs except single…
