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…

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…
