Thermal conductivity and the electron-ion heat transfer coefficient in condensed media with a strongly excited electron subsystem

The two-temperature (T e > T i ) thermal conductivity coefficient κ2T and electron-ion heat transfer coefficient α, which are necessary for the quantitative description of the processes initiated by ultrashort laser pulse, have been calculated using a kinetic equation, the matrix element for the scattering probability, and a screened Coulomb potential describing the interaction between charged particles. Quantitative information has been obtained for coefficients κ2T and α values for noble and transition metals, where the d-band electrons play a significant role.
