Spin susceptibility for liquid alkali metals

Research output: Contribution to journalArticlepeer-review


A theoretical method that permits a better understanding of the electronic spin susceptibility for liquid metals is proposed. This method combines the well-known Landau-Fermi liquid theory, the theory of jellium spin susceptibility, and a pseudopotential perturbative calculation of the density-of-state effective mass for a disordered liquid system, and it provides a novel viewpoint that links the usual rigorous many-body theory to the phenomenological Landau-Fermi liquid model. In this work, the role of electronic exchange-correlation corrections to the paramagnetism in a simple liquid metal is examined. By comparing the two best available theories of jellium spin susceptibility, it is found that much physical insight about the correlation effects can be gained, in addition to an accurate prediction of the magnitude of electronic spin susceptibility.
