Emergent superconductivity upon disordering a topological insulator
Carlos Eduardo S. P. Corsino, Hermann Freire, Anurag Banerjee
We study the emergence of superconductivity in a quantum spin Hall insulator and identify a disorder-driven enhancement of pairing arising from quantum geometry. Using sign-problem…

Exact analysis of the interplay of charge order and unconventional pairings in the 2D Hatsugai-Kohmoto model
Carlos Eduardo S. P. Corsino, Hermann Freire
We provide here a study of some competing ordering tendencies exhibited by the exactly solvable 2D Hatsugai-Kohmoto (HK) model on a square lattice. To this end, we investigate the…

Strong pair-density-wave fluctuations in an exactly solvable doped Mott insulator
Igor de M. Froldi, Carlos Eduardo S. P. Corsino, Hermann Freire
We investigate the Hatsugai-Kohmoto (HK) model on a square lattice, which describes both a Mott insulator at half-filling and a non-Fermi liquid phase on doping. Through the soluti…
