Anomalous Wave-Packet Dynamics in One-Dimensional Non-Hermitian Lattices
Yanyan He, Tomoki Ozawa
Non-Hermitian (NH) systems have attracted great attention due to their exotic phenomena beyond Hermitian domains. Here we study the wave-packet dynamics in general one-dimensional…

Quantized Hall drift in a frequency-encoded photonic Chern insulator
Alexandre Chénier, Bosco d'Aligny, Félix Pellerin +4
The quantization of transport and its resilience to backscattering are key features for leveraging topological matter in applications that demand stringent noise mitigation, such a…

Mean-chiral displacement in coherently driven photonic lattices and its application to synthetic frequency dimensions
Greta Villa, Iacopo Carusotto, Tomoki Ozawa
Characterizing topologically nontrivial photonic lattices by measuring their topological invariants is crucial in topological photonics. In conservative one-dimensional systems, a…
