Do Quantum AIs Dream in Paths? Path-Integral Slow Thinking through Grover Interference

Xiansheng Cai, Xiu-Hao Deng, Kun Chen

Reinforcement learning with verifiable rewards enables large language models to think slowly, but the same training can induce policy collapse: probability concentrates onto a few…

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…

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…

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…
