Causality Sum Rules in Conventional Scattering Matrices
Ning Han, Rui Zhao, Shuxing Yang +3
Scattering matrices are the standard experimental and computational description of photonic and electromagnetic devices. Passivity is explicit in the conventional incoming-outgoing…
Self-healing topological streams in space-time
Yudong Ren, Wenhao Li, Yuang Pan +2
Topological states are renowned for their robustness against perturbations. Recent advances have further introduced momentum-gap (or time) topology in time-varying media, enabling…
Observation of localization reversal and harmonic generation in nonlinear non-Hermitian skin effect
Junyao Wu, Rui-Chang Shen, Li Zhang +5
The interplay between band topology and material nonlinearity gives rise to a variety of novel phenomena, such as topological solitons and nonlinearity-induced topological phase tr…
End-to-end autonomous scientific discovery on a real optical platform
Shuxing Yang, Fujia Chen, Rui Zhao +10
Scientific research has long been human-led, driving new knowledge and transformative technologies through the continual revision of questions, methods and claims as evidence accum…
Non-diffusion transport in decoherent non-Hermitian quasicrystals
Yudong Ren, Rui Zhao, Kangpeng Ye +4
Disorder and coherence jointly govern wave transport in complex media. In Hermitian systems, a long-established paradigm since Anderson's work holds that disorder-induced localizat…
A scalable and programmable optical neural network in a time-synthetic dimension
Bei Wu, Yudong Ren, Rui Zhao +6
Programmable optical neural networks (ONNs) can offer high-throughput and energy-efficient solutions for accelerating artificial intelligence (AI) computing. However, existing ONN…
