Signatures of strong correlation effects in RIXS on Cuprates [PDF]
, 2016 Recently, spin excitations in doped cuprates are measured using the resonant inelastic X-ray scattering (RIXS). The paramagnon dispersions show the large hardening effect in the electron-doped systems and seemingly doping-independence in the hole-doped ...
