Spin-orbit coupled superconductivity: Rashba-Hubbard model on the square lattice
Sebastian Wolf, Stephan Rachel
The weak-coupling renormalization group method is an asymptotically exact method to find superconducting instabilities of a lattice model of correlated electrons. Here we extend it…
Laser modulation of superconductivity in a cryogenic widefield nitrogen-vacancy microscope
Scott E. Lillie, David A. Broadway, Nikolai Dontschuk +6
Microscopic imaging based on nitrogen-vacancy (NV) centres in diamond, a tool increasingly used for room-temperature studies of condensed matter systems, has recently been extended…
Unconventional superconductivity in the extended Hubbard model: Weak-coupling renormalization group
Sebastian Wolf, Thomas L. Schmidt, Stephan Rachel
We employ the weak-coupling renormalization group approach to study unconventional superconducting phases emerging in the extended, repulsive Hubbard model on paradigmatic two-dime…
Shallow-band superconductors: pushing superconductivity types apart
S. Wolf, A. Vagov, A. A. Shanenko +2
Magnetic response is a fundamental property of superconducting materials, which helps to distinguish two superconductivity types: the ideally diamagnetic type I and type II, which…
