Here we report on our project concerning the application of time dependent DMRG to strongly correlated systems. We show that a previously reported simulation of the spin charge separation in a one-dimensional Hubbard system exceeds a relative error of 100% in the spin sector. In the second part we discuss the application of the Kubo formula to obtain linear conductance for the interacting resonant level model.
