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…
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…
Efficiency of the superconducting diode effect of pair-density-wave states in two-dimensional -wave altermagnets
Igor de M. Froldi, Hermann Freire
We systematically study the efficiency of the intrinsic superconducting diode effect of several pair-density-wave states that can emerge in two-dimensional -wave metallic alterm…
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…
Unconventional superconductivity in altermagnets with spin-orbit coupling
Vanuildo S. de Carvalho, Hermann Freire
We investigate some possible symmetries of the superconducting state that emerges in three-dimensional altermagnets in the presence of spin-orbit coupling. We demonstrate within a…
Transport properties in non-Fermi liquid phases of nodal-point semimetals
Ipsita Mandal, Hermann Freire
In this review, we survey the current progress in computing transport properties in semimetals which harbour non-Fermi liquid phases. We first discuss the widely-used Kubo formalis…
Edge magnetization and spin transport in an SU(2)-symmetric Kitaev spin liquid
V. S. de Carvalho, H. Freire, E. Miranda +1
We investigate the edge magnetism and the spin transport properties of an SU(2)-symmetric Kitaev spin liquid (KSL) model put forward by Yao and Lee [Phys. Rev. Lett. \textbf{107},…
