| 内容記述 | We propose a semi-classical approach based on the Vlasov equation to describe the time-dependentelectronic dynamics in a bulk simple metal under an ultrashort intense laser pulse. We include in theeffective potential not only the ionic Coulomb potential and mean-field electronic Coulomb potentialfrom the one-body electron distribution but also the exchange-correlation potential within the localdensity approximation (LDA). The initial ground state is obtained by the Thomas-Fermi model.To numerically solve the Vlasov equation, we extend the pseudo-particle method, previously usedfor nuclei and atomic clusters, to solids, taking the periodic boundary condition into account. Weapply the present implementation to a bulk aluminum (FCC) conventional unit cell irradiated witha short laser pulse. The optical conductivity, refractive index, extinction coefficient, and reflectivityas well as energy absorption calculated with the Vlasov-LDA method are in excellent agreementwith the results by the time-dependent density functional theory and experimental references | |||||
