Superconducting state of SrRuO in the presence of longer-range Coulomb interactions
Astrid T. Rømer, P. J. Hirschfeld, Brian M. Andersen
The symmetry of the superconducting condensate in SrRuO remains controversial after nuclear magnetic resonance (NMR) experiments recently overturned the dominant chiral …
Orbital-dependent self-energy effects and consequences for the superconducting gap structure in multi-orbital correlated electron systems
Kristofer Björnson, Andreas Kreisel, Astrid T. Rømer +1
We perform a theoretical study of the effects of electronic correlations on the superconducting gap structure of multi-band superconductors. In particular, by comparing standard RP…
Nature of the magnetic stripes in fully oxygenated LaCuO
Ana-Elena Tutueanu, Henrik Jacobsen, Pia Jensen Ray +12
We present triple-axis neutron scattering studies of static and dynamic magnetic stripes in an optimally oxygen-doped cuprate superconductor, LaCuO, which exhibits a…
Theory of Strain-Induced Magnetic Order and Splitting of and in SrRuO
Astrid T. Rømer, Andreas Kreisel, Marvin A. Müller +3
The internal structure of the superconducting state in SrRuO remains elusive at present, and exhibits evidence for time-reversal symmetry breaking. Recent muon spin relaxat…
Fluctuation-driven superconductivity in SrRuO from weak repulsive interactions
Astrid T. Rømer, Brian M. Andersen
We provide results for the leading superconducting instabilities for a model pertaining to SrRuO obtained within spin-fluctuation mediated superconductivity in the very wea…
Pairing in the Two-Dimensional Hubbard Model from Weak to Strong Coupling
Astrid T. Rømer, Thomas A. Maier, Andreas Kreisel +3
The Hubbard model is the simplest model that is believed to exhibit superconductivity arising from purely repulsive interactions, and has been extensively applied to explore a vari…
