Probing the Critical Point (CritPt) of AI Reasoning: a Frontier Physics Research Benchmark
Minhui Zhu, Minyang Tian, Xiaocheng Yang +61
While large language models (LLMs) with reasoning capabilities are progressing rapidly on high-school math competitions and coding, can they reason effectively through complex, ope…
Neural Network Discovery of Paired Wigner Crystals in Artificial Graphene
Conor Smith, Yubo Yang, Zhou-Quan Wan +3
Moiré systems have emerged as an exciting tunable platform for engineering and probing quantum matter. A large number of exotic states have been observed, stimulating intense effo…
Engineering Hubbard models with gated two-dimensional moiré systems
Yiqi Yang, Yubo Yang, Miguel A. Morales +1
Lattice models are powerful tools for studying strongly correlated quantum many-body systems, but their general lack of exact solutions motivates efforts to simulate them in tunabl…
Quantum Geometry Driven Crystallization: A Neural-Network Variational Monte Carlo Study
Agnes Valenti, Yaar Vituri, Yubo Yang +7
Wigner crystals are a paradigmatic form of interaction driven electronic order. A key open question is how Berry curvature and, more generally, quantum geometry reshape crystalliza…
Visualizing the Impact of Quenched Disorder on 2D Electron Wigner Solids
Zhehao Ge, Conor Smith, Zehao He +17
Electron Wigner solids (WSs)1-12 provide an ideal system for understanding the competing effects of electron-electron and electron-disorder interactions, a central unsolved problem…
Critical gate distance for Wigner crystallization in the two-dimensional electron gas
Agnes Valenti, Vladimir Calvera, Yubo Yang +4
We report on the properties of the two-dimensional electron gas in a dual-gate geometry, using quantum Monte Carlo methods to obtain aspects of the phase diagram as a function of e…
