Recursive Improvement of a Differentiable Scientific Software Ecosystem
Pengcheng Hou, Xiaojun Tan, Sihan Hu +5
Differentiable programming connects scientific computation with gradient-based inference, learning and design. Extending these capabilities across a heterogeneous software ecosyste…
Long-range self-avoiding walk in one dimension: a Monte Carlo study
Jiang Zhou, Ziyu Liu, Pengcheng Hou +2
We study the one-dimensional long-range self-avoiding walk in the grand-canonical ensemble where the statistical weight of a jump of length decays algebraically as …
The Expansion for Long-Range Lee--Yang and Percolation Criticality
Zhiyi Li, Kun Chen, Zhijie Fan +1
The crossover from long-range (LR) to short-range (SR) criticality in percolation has remained unsettled because previous renormalization-group (RG) analysis within the e…
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…
Static spin exchange-correlation kernel of the uniform electron gas at finite temperature
Pengcheng Hou, Zhiyi Li, Youjin Deng +1
We determine the temperature and momentum dependence of the static spin exchange--correlation kernel of the unpolarized three-dimensional uniform electron gas using variational dia…
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…
The 4- Expansion for Long-range Interacting Systems
Zhiyi Li, Kun Chen, Youjin Deng
The establishment of the Wilson-Fisher fixed point (WFP) for spin models in dimensions stands as a cornerstone of the renormalization group (RG) theory for critical…
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.…
Inverse Knowledge Search over Verifiable Reasoning: Synthesizing a Scientific Encyclopedia from a Long Chains-of-Thought Knowledge Base
Yu Li, Yuan Huang, Tao Wang +19
Most scientific materials compress reasoning, presenting conclusions while omitting the derivational chains that justify them. This compression hinders verification by lacking expl…
Tensor Network Markov Chain Monte Carlo: Efficient Sampling of Three-Dimensional Spin Glasses and Beyond
Tao Chen, Jing Liu, Youjin Deng +1
Sampling the three-dimensional (3D) spin glass -- i.e., generating equilibrium configurations of a 3D lattice with quenched random couplings -- is widely regarded as one of the cen…
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…
Learning-at-Criticality in Large Language Models for Quantum Field Theory and Beyond
Xiansheng Cai, Sihan Hu, Tao Wang +4
Fundamental physics often confronts complex symbolic problems with few guiding exemplars or established principles. While artificial intelligence (AI) offers promise, its typical n…
Matsubara-Frequency-Resolved Spin Exchange-Correlation Kernel for the Three-Dimensional Uniform Electron Gas
Zhiyi Li, Pengcheng Hou, Youjin Deng +1
The spin Coulomb drag effect, arising from the exchange of momentum between electrons of opposite spins, plays a crucial role in the spin transport of interacting electron systems…
An AI-powered Technology Stack for Solving Many-Electron Field Theory
Pengcheng Hou, Tao Wang, Daniel Cerkoney +5
Quantum field theory (QFT) for interacting many-electron systems is fundamental to condensed matter physics, yet achieving accurate solutions confronts computational challenges in…
