Shape of Wigner Crystals and Hole Self-Doping in a Mexican-Hat Dispersion
Minho Luke Kim, Xiao-Gang Wen
We study Wigner crystals (WCs) induced by a strong Coulomb interaction from the ring-like Fermi surface of a Mexican-hat dispersion . We design orbital shape in…

Symmetry-Enforced Fermi Surfaces
Minho Luke Kim, Salvatore D. Pace, Shu-Heng Shao
We identify a symmetry that enforces every symmetric model to have a Fermi surface. These symmetry-enforced Fermi surfaces are realizations of a powerful form of symmetry-enforced…

Topological chiral superconductivity beyond pairing in a Fermi liquid
Minho Kim, Abigail Timmel, Long Ju +1
We investigate a mechanism to produce superconductivity by strong purely repulsive interactions for flat dispersion , without using pairing instability in Fer…
