Kind: research · Impact: medium

## In brief

- The paper reports a first-principles study of the quasiparticle effective mass m* of the three-dimensional uniform electron gas.
- The effective mass is described as a fundamental Fermi-liquid parameter whose value and density dependence are the subject of the study.
- The work is published by the American Physical Society under DOI 10.1103/b8qp-v38m, with nine listed authors.

## Why it matters

The effective mass is a basic parameter of Fermi-liquid theory that shapes how electrons behave in metals, so a first-principles value for the uniform electron gas gives theorists and computational scientists a reference point.
