Fig. 9: Longer-chain results.

a Time evolution of return probability as a function of W_z at fixed g_x = 1 obtained by applying the Krylov-typicality method to periodic chains. The light to solid colors give the results of L = 21, 23, 25. b A sample calculation on a small chain illustrates that Krylov-typicality approximation reproduces the results of ED.
