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…
Slave-rotor theory of correlated altermagnets on the Lieb lattice
Vanuildo S. de Carvalho, Hermann Freire, Rodrigo G. Pereira
We investigate the metal-insulator transition driven by the onsite repulsive interaction in an altermagnetic Hubbard model defined on a Lieb lattice. Using the slave-rotor appr…
Superconducting diode effect in unconventional -wave magnets
Igor de M. Froldi, Hermann Freire
We investigate the emergence of superconducting phases, both with zero and finite Cooper-pair center-of-mass momenta, in recently proposed unconventional -wave magnets. As a res…
