The finite-T DMRG method is applied to the one-dimensional Kondo latticemodel to calculate dynamic correlation functions. Dynamic spin and chargecorrelations, S_f(omega), S_c(omega), and N_c(omega), and quasiparticle densityof states rho(omega) are calculated in the paramagnetic metallic phase forvarious temperatures and hole densities. Near half filling, it is shown that apseudogap grows in these dynamic correlation functions below the crossovertemperature characterized by the spin gap at half filling. A sharp peak atomega=0 evolves at low temperatures in S_f(omega) and N_c(omega). This may bean evidence of the formation of the collective excitations, and this confirmsthat the metallic phase is a Tomonaga-Luttinger liquid in the low temperaturelimit.Comment: 5 pages, 6 Postscript figures, REVTe
