Fig. 4: Pump-induced modification of spin excitation energy and pairing correlations.
From: X-ray scattering from light-driven spin fluctuations in a doped Mott insulator

a Equilibrium (gray) and maximal transient (colored) change of hole concentration and spin excitation energy (extracted from time-resolved resonant inelastic x-ray scattering spectral peaks) for the pump conditions in panel Fig. 3 at half-filling and 16.7% hole doping, respectively. b Corresponding dynamics of the d-wave pairing correlations.
