Anderson localization versus hopping asymmetry in a disordered lattice

Within the framework of non-Hermitian photonics, the authors investigate the interplay between disorder and non-Hermiticity in a one-dimensional disordered lattice. They show that the competition between the effects of disorder and non-Hermiticity results in qualitatively distinct phases of wave diffraction, including counterintuitive characteristics regarding the relation between the strength of disorder and the wave packet's velocity.
