Abstract

Understanding the interplay between charge, nematic, and structural ordering tendencies in cuprate superconductors is critical to unraveling their complex phase diagram. Using pump-probe time-resolved resonant X-ray scattering on the (0 0 1) Bragg peak at the Cu L3 and O K resonances, we investigate nonequilibrium dynamics of Qa = Qb = 0 nematic order and its association with both charge density wave (CDW) order and lattice dynamics in La1:65Eu0:2Sr0:15CuO4. The orbital selectivity of the resonant X-ray scattering cross-section allows nematicity dynamics associated with the planar O 2p and Cu 3d states to be distinguished from the response of anisotropic lattice distortions.Adirect time-domain comparison ofCDWtranslationalsymmetry breaking and nematic rotational-symmetry breaking reveals that these broken symmetries remain closely linked in the photoexcited state, consistent with the stability of CDW topological defects in the investigated pump fluence regime.
