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 [Formula see text] and O [Formula see text] resonances, we investigate nonequilibrium dynamics of [Formula see text] nematic order and its association with both charge density wave (CDW) order and lattice dynamics in La[Formula see text]Eu[Formula see text]Sr[Formula see text]CuO[Formula see text]. The orbital selectivity of the resonant X-ray scattering cross-section allows nematicity dynamics associated with the planar O 2[Formula see text] and Cu 3[Formula see text] states to be distinguished from the response of anisotropic lattice distortions. A direct time-domain comparison of CDW translational-symmetry 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.
