A dynamical order parameter for the transition to nonergodic dynamics in the discrete nonlinear Schrödinger equation

Andrew Kalish, Pedro Fittipaldi de Castro, Wladimir A. Benalcazar

The discrete nonlinear Schrödinger equation (DNLSE) exhibits a transition from ergodic, delocalized dynamics to a weakly nonergodic regime characterized by breather formation; yet,…
