Monopole Superconductivity in Magnetically Doped CdAs
Eric Bobrow, Yi Li
When superconducting pairing occurs between Fermi surfaces with different Chern numbers, the Cooper pairs possess nontrivial pair Berry phase, which enforces pairing gap nodes. The…
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…
Hund's coupling-assisted ferromagnetic percolation transition in a multiorbital flat band
Eric Bobrow, Junjia Zhang, Yi Li
By connecting Hund's physics with flat band physics, we establish an exact result for studying ferromagnetism in a multiorbital system. We consider a two-layer model consisting of…
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…
Stability of the Nagaoka-type Ferromagnetic State in a Orbital System on a Cubic Lattice
Eric Bobrow, Yi Li
We generalize the previous exact results of the Nagaoka-type itinerant ferromagnetic states in a three dimensional -orbital system to allow for multiple holes. The system i…
