Two-temperature kinetic coefficients of liquid aluminum in the conditions arising under the action of a femtosecond laser pulse

Abstract

Resistivity and thermal conductivity coefficient are calculated in the framework of Ziman approach. Resistivity is calculated as a reverse conductivity with the use of the relaxation time approximation accompanied by its calculation using Ziman–Evans formula. Both resistivity and thermal conductivity and Lorenz number are calculated as in the equilibrium one-temperature state and the two-temperature situation with different electron and ion temperatures. Influence of different approaches to the screening of electron–ion interactions when considering the kinetic coefficients is investigated.
