Universal Spreading Dynamics in Quasiperiodic Non-Hermitian Systems
Universal Spreading Dynamics in Quasiperiodic Non-Hermitian Systems
Non-Hermitian systems exhibit a distinctive type of wave propagation, due to the intricate interplay of non-Hermiticity and disorder. Here, we investigate the spreading dynamics in the archetypal non-Hermitian Aubry-Andr\'e model with quasiperiodic disorder. We uncover counter-intuitive transport behaviors: subdiffusion with a spreading exponent $\delta=1/3$ in the localized regime and diffusion …
