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…
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…
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…
Photonic antiferromagnetic topological insulator with a single surface Dirac cone
Fujia Chen, Ning Han, Songyang Pu +12
Antiferromagnetism, characterized by magnetic moments aligned in alternating directions with a vanished ensemble average, has garnered renewed interest for its potential applicatio…
Three-dimensional topological valley photonics
Wenhao Li, Qiaolu Chen, Ning Han +8
Topological valley photonics, which exploits valley degree of freedom to manipulate electromagnetic waves, offers a practical and effective pathway for various classical and quantu…
Observation of temporal topological boundary states of light in a momentum bandgap
Yudong Ren, Kangpeng Ye, Qiaolu Chen +8
Topological phases have prevailed across diverse disciplines, spanning electronics, photonics, and acoustics. Hitherto, the understanding of these phases has centred on energy (fre…
