Thermal Conductivity and the Electron-Ion Heat Transfer Coefficient in Condensed Media with a Strongly Excited Electron Subsystem
TL;DR: In this paper, the two-temperature thermal conductivity coefficient and electron-ion heat transfer coefficient α, which are necessary for the quantitative description of the processes initiated by ultrashort laser pulse, were calculated using a kinetic equation, the matrix element for the scattering probability, and a screened Coulomb potential describing the interaction between charged particles.

Solitary Nanostructures Produced by Ultrashort Laser Pulse
TL;DR: A simple physical model describing mechanisms happened in a thin metal film on dielectric substrate irradiated by a tightly focused ultrashort laser pulse and developed theory opens door for optimizing laser parameters for intended nanostructuring in applications.
