Quench dynamics in nonreciprocal Aubry-Andr\'e-Harper model
The critical phase of a non-Hermitian quasicrystal can support stronger transport than its surrounding delocalized phase. We demonstrate this anomalous behavior in the one-dimensional nonreciprocal Aubry-Andr\'e-Harper model through a combined study of dynamical quantum phase transitions (DQPTs) and wavepacket diffusio...
