We study the equilibration behavior following local quenches, usingfrustrated quantum spin chains as an example of interacting closed quantumsystems. Specifically, we examine the statistics of the time series of theLoschmidt echo, the trace distance of the time-evolved local density matrix toits average state, and the local magnetization. Depending on the quenchparameters, the equilibration statistics of these quantities show features ofgood or poor equilibration, indicated by Gaussian, exponential or bistabledistribution functions. These universal functions provide valuable tools tocharacterize the various time-evolution responses and give insight into theplethora of equilibration phenomena in complex quantum systems.
