Investigate the dynamic effects of flux quenching in the Su-Schrieffer-Heeger model of a 1-D ring geometry. We find that the flux quench induces a time-dependent current that eventually reaches a finite steady-state value, even when the system is initially in a half-filled isolation state. Such persistent currents, which also exist in the thermodynamic limit, cannot be captured by linear response theory and are characteristic of nonlinear dynamic effects occurring in the presence of dimerization. Furthermore, we show that for a range of values ​​of dimerization intensity and initial flux, the system exhibits a dynamic quantum phase transition even though the quenching is performed within the same topology class of the model.
