Universal Spreading Dynamics in Quasiperiodic Non-Hermitian Systems
In a quasiperiodic non-Hermitian lattice, wave packets spread diffusively with exponent 1/2 in the delocalized phase and subdiffusively with exponent 1/3 in the localized phase, in contrast to ballistic and halted Hermitian dynamics.
