Large-Scale Autonomous Discovery of Kissing Number Constructions
Shuxing Yang, Rui Zhao, Junyao Wu +13
The kissing-number problem is a classical problem in discrete geometry whose exact solution is known in only a few dimensions. Recent artificial-intelligence approaches have begun…
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…
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…
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…
Realizing anomalous Floquet non-Abelian band topology in photonic scattering networks
Yuze Hu, Mingyu Tong, Tian Jiang +10
The concept of multi-gap topology has recently been shown to give rise to uncharted phases beyond conventional single-gap classifications. These phases relate to band nodes with no…
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…
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…
