Complex-gauge control of anomalous Floquet corner responses in a non-Hermitian physical-synthetic photonic lattice

arXiv:2606.07038v1 Announce Type: new Abstract: We propose a non-Hermitian Floquet photonic lattice formed by a physical resonator coordinate and a synthetic frequency coordinate. A two-step modulation protocol realizes a chiral walk in this physical-synthetic plane, with a real synthetic flux cont
