 note = {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},
