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…
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…
Kohn-Sham Hamiltonian from Effective Field Theory: Quasiparticle Band Narrowing from Frozen Core Dynamics
Xiansheng Cai, Han Wang, Kun Chen
Kohn-Sham (KS) eigenvalues are routinely compared with angle-resolved photoemission (ARPES) and used as input for many-body methods, yet density functional theory (DFT) assigns the…
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…
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…
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…
