SciCode-Verified: How Benchmark Defects Underestimated the Scientific-Coding Ability of Language Models
Sihan Hu, Lyuhan Huang, Youjin Deng +1
SciCode is the standard measure of the scientific-coding ability of language models: research-level problems that demand both frontier scientific theory and its implementation as w…
Perturbative Renormalization and Universality Diagram for Long-Range Quantum Criticality
Zhiyi Li, Zhijie Fan, Kun Chen +1
Experimental progress in quantum simulators highlights the role of long-range (LR) interactions in reshaping quantum criticality and stabilizing exotic phases beyond the short-rang…
Two-Electron Correlations in the Metallic Electron Gas
Zhiyi Li, Pengcheng Hou, Bao-Zong Wang +2
We present high-precision \emph{ab initio} calculations of the four-point vertex function for the three-dimensional uniform electron gas using variational diagrammatic Monte Carlo.…
Finite-Temperature Spin Exchange-Correlation Kernel of the Uniform Electron Gas
Pengcheng Hou, Zhiyi Li, Youjin Deng +1
The finite-temperature spin response of the uniform electron gas (UEG) is a fundamental reference for spin-polarized and magnetized electron liquids, including warm dense matter (W…
Emergent Slow Thinking in LLMs as Inverse Tree Freezing
Sihan Hu, Xiansheng Cai, Yuan Huang +5
Reinforcement learning with verifiable rewards (RLVR) enables large language models to acquire slow, multi-step reasoning from sparse final-answer signals. We provide a statistical…
First-Principles Effective Mass in the Three-Dimensional Uniform Electron Gas
Pengcheng Hou, Daniel Cerkoney, Zhiyi Li +6
The quasiparticle effective mass of the three-dimensional uniform electron gas (UEG) is a fundamental Fermi-liquid parameter whose value and density dependence have remained…
