Light-cone velocities after a global quench in a noninteracting model
We study the light-cone velocity for global quenches in the noninteracting XY chain starting from a class of initial states that are eigenstates of the localzcomponent of the spin. We point out how translation invariance of the initial state can affect the maximal speed at which correlations spread...
