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… 
Physical and unphysical regimes of self-consistent many-body perturbation theory
In the standard framework of self-consistent many-body perturbation theory, the skeleton series for the self-energy is truncated at a finite order N and plugged into the Dyson equation, which is then
M* of Two-dimensional Electron Gas: a Neural Canonical Transformation Study
TLDR
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.

A combined variational and diagrammatic quantum Monte Carlo approach to the many-electron problem
TLDR
It is shown that combining Feynman diagram technique and diagrammatic quantum Monte Carlo method results in a powerful and accurate solver to the generic solid state problem, in which a macroscopic number of electrons interact by the long range Coulomb repulsion.
Dynamical local-field factors and effective interactions in the three-dimensional electron liquid.
TLDR
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.
Diagrammatic Monte Carlo for correlated fermions
We show that Monte Carlo sampling of the Feynman diagrammatic series (DiagMC) can be used for tackling hard fermionic quantum many-body problems in the thermodynamic limit by presenting accurate
