A path to superconductivity via strong short-range repulsion in a spin-polarized band
Zhiyu Dong, Patrick A. Lee
We predict that the spin-polarized electrons in a two-dimensional triangular lattice with strong electron-electron repulsion gives rise to f-wave pairing. The key point is that the…

A controlled expansion for pairing in a polarized band with strong repulsion
Zhiyu Dong, Patrick A. Lee
Can strong repulsive interactions be shown to give rise to pairing in a controlled way? We find that for a single flavor polarized band, there is a small expansion parameter in the…

Chirality-induced pseudo-magnetic fields, flat bands and enhancement of superconductivity
Zhiyu Dong, Leonid Levitov, Patrick A. Lee
Systems in which exchange interactions couple carrier spins to a spin texture with a net chirality exhibit a spin-dependent Aharonov-Bohm effect, where the geometric gauge field an…
