@article{Haule2022SingleparticleEI, title={Single-particle excitations in the uniform electron gas by diagrammatic Monte Carlo}, author={Kristjan Haule and Kun Chen}, journal={Scientific Reports}, year={2022}, volume={12} }

We calculate the single-particle excitation spectrum and the Landau liquid parameters for the archetypal model of solids, the three-dimensional uniform electron gas, with the variational diagrammatic Monte Carlo method, which gives numerically controlled results without systematic error. In the metallic range of density, we establish benchmark values for the wave-function renormalization factor Z, the effective mass \documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym…

The newly developed neural canonical transformation approach offers a principled way to extract the effective mass of electron gas by directly calculating the thermal entropy at low temperature, and reveals a suppression of effective mass in the two-dimensional spin-polarized electron gas.

An analytical study of the dynamical local-field factors associated with the response of a homogeneous two-dimensional interacting electron liquid as functions of momentum, frequency, and density and shows that both the quantitative and qualitative behaviors of the interaction are sensitive to the inclusion of dynamical correlations.
