Anomalous transport in quasiperiodic lattices: emergent exceptional points at band edges and log-periodic oscillations
Jinyuan Shang, Haiping Hu
Quasiperiodic systems host exotic transport regimes that are distinct from those found in periodic or disordered lattices. In this work, we study quantum transport in the Aubry-And…

Anisotropic Anderson localization in higher-dimensional nonreciprocal lattices
Jinyuan Shang, Haiping Hu
Nonreciprocity breaks the symmetry between forward and backward propagation, giving rise to a range of peculiar wave phenomena. In this work, we investigate Anderson localization i…

Spreading dynamics in the Hatano-Nelson model with disorder
Jinyuan Shang, Haiping Hu
The non-Hermitian skin effect is the accumulation of eigenstates at the boundaries, reflecting the system's nonreciprocity. Introducing disorder leads to a competition between the…
