AB We study holographic models related to global quantum quenches in finite sizesystems. The holographic set up describes naturally a CFT, which we consider on a circleand a sphere. The enhanced symmetry of the conformal group on the circle motivatesus to compare the evolution in both cases. Depending on the initial conditions, the dualgeometry exhibits oscillations that we holographically interpret as revivals of the initialfield theory state. On the sphere, this only happens when the energy density created bythe quench is small compared to the system size. However on the circle considerably largerenergy densities are compatible with revivals. Two different timescales emerge in thislatter case. A collapse time, when the system appears to have dephased, and the revivaltime, when after rephasing the initial state is partially recovered. The ratio of these twotimes depends upon the initial conditions in a similar way to what is observed in someexperimental setups exhibiting collapse and revivals
