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…
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…
Observation of Custodial Chiral Symmetry in Memristive Topological Insulators
Wenhao Li, Junyao Wu, Ning Han +8
The concept of custodial symmetry, a residual symmetry that protects physical observables from large quantum corrections, has been a cornerstone of high-energy physics, but its exp…
Realization of Weyl elastic metamaterials with spin skyrmions
Yuang Pan, Liang Si, Miao Yang +18
Topological elastic metamaterials provide a topologically robust way to manipulate the phononic energy and information beyond the conventional approaches. Among various topological…
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…
