Calculation of the electrical conductivity of a cesium melt by an LMTO recursive method over a wide temperature range

The structure and properties of liquid cesium are calculated over a wide temperature range. The Shommers method, which is based on Winter’s experimental data, is used to construct structural models. A density of states is obtained by a recursive method using an LMTO Hamiltonian. Electrical conductivity is calculated by the Kubo-Greenwood formula. The degree of electron localization as a function of temperature is estimated, and the metal-nonmetal transition in cesium is shown to be related to electron localization at atomic clusters.
