title = "Nonequilibrium lattice-driven dynamics of stripes in nickelates using time-resolved x-ray scattering",
abstract = "We investigate the lattice coupling to the spin and charge orders in the striped nickelate, La1.75Sr0.25NiO4, using time-resolved resonant x-ray scattering. Lattice-driven dynamics of both spin and charge orders are observed when the pump photon energy is tuned to that of an Eu bond- stretching phonon. We present a likely scenario for the behavior of the spin and charge order parameters and its implications using a Ginzburg-Landau theory.",
