Electrical Resistivity of Liquid Alkali Metals (Na and K): A Pseudopotential Study Using the HFP (Harrison-Faber-Ziman) Technique

Dr. Ravi Shanker Prasad, Dr. Kanchan Kumar

Abstract: A quantitative theoretical study of the electrical resistivity of liquid sodium (Na) and potassium (K) is presented using the pseudopotential formalism within the Harrison-Faber-Ziman (HFP) technique. Numerical calculations are carried out using Ashcroft empty-core pseudopotentials and experimentally motivated static structure factors. Electrical resistivity values are computed at different temperatures above the melting point and compared with experimental trends. Tables of resistivity, pseudopotential parameters, and structure-factor characteristics are presented. Graphical representations of temperature-dependent resistivity demonstrate the validity of the HFP approach for simple liquid metals.

Keywords: electrical resistivity, liquid sodium and potassium, pseudopotential method, temperature dependent behavior, simple liquid metals
