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…
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…
Percolation in the three-dimensional Ising model
Jinhong Zhu, Tao Chen, Zhiyi Li +2
Geometric representations provide a useful perspective on critical phenomena in the Ising model. In a recent study [Phys. Rev. E 112, 034118 (2025)], we found that the two-dimensio…
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.…
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…
