Robust quantized transport from topological quasienergy winding in long-range-coupling synthetic quantum walks
Chengzhi Qin, Yinglan Li, Bing Wang +5
Quantized transport is a prominent feature in topological physics, with canonical examples being the quantum Hall effect and adiabatic Thouless pump, which are based on the Chern n…
Universal convolution from wave dynamics: photonic processing and encryption in synthetic dimension
Xiaolong Su, Weiwei Liu, Ruiqian Cheng +6
Convolution, a cornerstone of signal processing and optical neural networks, has traditionally been implemented by mapping mathematical operations onto complex hardware. Here, we o…
Reconfigurable chiral edge states in synthetic dimensions on an integrated photonic chip
Weiwei Liu, Xiaolong Su, Chijun Li +7
Chiral edge state is a hallmark of topological physics, which has drawn significant attention across quantum mechanics, condensed matter and optical systems. Recently, synthetic di…
Nonlinear Non-Hermitian Skin Effect and Skin Solitons in Temporal Photonic Feedforward Lattices
Shulin Wang, Bing Wang, Chenyu Liu +5
Here we report the experimental demonstration of the nonlinear non-Hermitian skin effect (NHSE) in an effective Kerr nonlinear temporal photonic lattice, where the high-power requi…
Spectrum Cascade Bloch Oscillations in Temporally Modulated Acoustics
Chengzhi Qin, Yugui Peng, Ying Li +4
Bloch oscillations (BOs) refer to a periodically oscillatory motion of particle in lattice systems driven by a constant force. By temporally modulating acoustic waveguides, BOs can…
Frequency manipulation of light by photonic gauge potentials

The ability to manipulate the frequency of light is of great importance in both fundamental quantum sciences and practical applications. Traditional method for frequency conversion…
Exceptional Points and Asymmetric Mode Switching in Plasmonic Waveguides
Shaolin Ke, Bing Wang, Chengzhi Qin +3
We investigate the exceptional points (EPs) in a non-Hermitian system composed of a pair of graphene sheets with different losses. There are two surface plasmon polaritons (SPP) mo…
