Data-Efficient Language Modeling: From Frontier Advancement to Principle-Guided Model Improvement
Shuxing Yang, Kaihao Zhu, Junjie Yang +13
Learning from limited text requires models to use context, generalize to new inputs, and retain useful capabilities. Qiushi Engine conducted a long-horizon, end-to-end autonomous r…
Qiushi Engine on AstaBench E2E-Bench-Hard
Wenhao Li, Shuxing Yang, Fujia Chen +13
This report analyzes Qiushi Engine v0.8 across all 40 test tasks in AstaBench E2E-Bench-Hard, a benchmark that requires autonomous agents to carry a research question through exper…
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 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…
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

Boundary-induced topological chiral extended states in Weyl metamaterial waveguides
Ning Han, Fujia Chen, Mingzhu Li +9
In topological physics, it is commonly understood that the existence of the boundary states of a topological system is inherently dictated by its bulk. A classic example is that th…
Real higher-order Weyl photonic crystal
Yuang Pan, Chaoxi Cui, Qiaolu Chen +9
Higher-order Weyl semimetals are a family of recently predicted topological phases simultaneously showcasing unconventional properties derived from Weyl points, such as chiral anom…
Demonstration of broadband topological slow light
Fujia Chen, Haoran Xue, Yuang Pan +12
Slow-light devices are able to significantly enhance light-matter interaction due to the reduced group velocity of light, but a very low group velocity is usually achieved in a nar…
Discovery of a maximally charged Weyl point
Qiaolu Chen, Fujia Chen, Qinghui Yan +7
The hypothetical Weyl particles in high-energy physics have been discovered in three-dimensional crystals as collective quasiparticle excitations near two-fold degenerate Weyl poin…
