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 from repulsive interactions on the kagome lattice
Astrid T. Rømer, Shinibali Bhattacharyya, Roser Valentí +2
The discovery of superconductivity in layered vanadium-based kagome metals VSb (: K, Rb, Cs) has added a new family of materials to the growing class of possible unco…
Leading superconducting instabilities in three-dimensional models for Sr2RuO4
Astrid T. Rømer, T. A. Maier, Andreas Kreisel +2
The superconductor Sr2RuO4 has been the subject of enormous interest over more than two decades, but until now the form of its order parameter has not been determined. Since ground…
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…
Evolution of magnetic stripes under uniaxial stress in LaBaCuO studied by neutron scattering
Machteld E. Kamminga, Kristine M. L. Krighaar, Astrid T. Rømer +6
Here we present the effect of uniaxial stress on the magnetic stripes in the cuprate system LaBaCuO with , previously found to have a stress-induced en…
