Ab Initio Thermodynamic Results for the Degenerate Electron Gas at Finite Temperature.

摘要: The uniform electron gas at finite temperature is of key relevance for many applications in dense plasmas, warm matter, laser excited solids, and much more. Accurate thermodynamic data the are an essential ingredient many-body theories, particular, density-functional theory. Recently, first-principles restricted path integral Monte Carlo results became available, which, however, had to be moderate degeneracy, i.e., low densities with r_{s}=r[over ¯]/a_{B}≳1. Here we present novel configuration electrons r_{s}≤4. We also quantum statistical within e^{4} approximation that good agreement simulations small r_{s}.
