Revisiting superconductivity in the extended one-band Hubbard model: pairing via spin and charge fluctuations
Mercè Roig, Astrid T. Rømer, P. J. Hirschfeld +1
The leading superconducting instabilities of the two-dimensional extended repulsive one-band Hubbard model within spin-fluctuation pairing theory depend sensitively on electron den…
Heat capacity double transitions in time-reversal symmetry broken superconductors
Henrik S. Røising, Glenn Wagner, Mercè Roig +2
Standard superconductors display a ubiquitous discontinuous jump in the electronic specific heat at the critical superconducting transition temperature. In a growing class of uncon…
Superconductivity in multiorbital systems with repulsive interactions: Hund's pairing vs. spin-fluctuation pairing
Mercè Roig, Astrid T. Rømer, Andreas Kreisel +2
Hund's pairing refers to Cooper pairing generated by onsite interactions that become attractive due to large Hund's exchange . This is possible in multiorbital systems even when…
