Wave-packet spreading in the disordered and nonlinear Su-Schrieffer-Heeger chain
Nonlinearity in the disordered SSH chain causes asymptotic wave-packet spreading to become independent of topological parameters due to mode interactions, unlike the linear case with anomalous diffusion at the transition.
