Electrical resistivity of liquid K-Rb-Cs alloys

A model potential consisting of varying cancellation of attractive and repulsive potentials within the core is applied for the first time to study the electrical resistivity of liquid K-Rb-Cs alloys. The influence of exchange and correlation effects are also studied by including local-field correlation functions due to Hartree, Taylor, Ichimaru-Utsumi, Farid et al. and Sarkar et al. The results for electrical resistivity of pure metallic components (K, Rb and Cs), liquid binaries (K-Rb, Rb-Cs and K-Cs) and liquid ternary (K-Rb-Cs) favours the formulation of our new model potential. The comparison of present results with those obtained due to self-consistent energy independent model potential and experimental findings also confirm the validity of our model in the study of ternary alloys.
