Separate tuning of nematicity and spin fluctuations to unravel the origin of superconductivity in FeSe
...
The interplay of orbital and spin degrees of freedom is the fundamental characteristic in numerous condensed matter phenomena, including high-temperature superconductivity, quantum spin liquids, and topological semimetals. In iron-based superconductors (FeSCs), this causes superconductivity to emerge in the vicinity of two other instabilities: nema...
Probing the energy gap of high-temperature cuprate superconductors by resonant inelastic x-ray scattering

A new way to characterize the symmetry of the superconducting gap might help to understand the microscopic mechanism of unconventional superconductivity. Resonant inelastic x-ray scattering (RIXS) is a momentum-resolved, bulk-sensitive technique that is applicable to a wide range of superconductors, as it doesn’t require the use of large single cry...
