Complex-gauge control of anomalous Floquet corner responses in a non-Hermitian physical-synthetic photonic lattice
W. C. Ning, X. Z. Zhang
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…

Boundary logical subspace and bulk dynamical probes in flux-controlled anomalous Floquet quantum walks
WeiCheng Ning, YanSheng Liu, XiaoXue Zhang +1
We formulate a one-dimensional flux-controlled anomalous Floquet quantum walk and show that it admits a direct microscopic realization in a driven bipartite lattice. The walk consi…
