We review recent experimental and theoretical results on the interaction between single-particle excitations and collective spin excitations in the superconducting state of high-Tc cuprates. We…
Evidence for unidirectional nematic bond ordering in FeSe
The presence of ${d}_{xz}\text{\ensuremath{-}}{d}_{yz}$ orbital ordering is often considered a hallmark of the nematic phase of Fe-based superconductors, including FeSe, but the details of the order…
