We investigate the separation of spin and charge in interacting one-dimensional fermion systems. Density matrix renormalisation group (DMRG) simulations on the Hubbard model in the time domain show this phenomenon explicitely in a transport scenario. The separation of internal degrees of freedom and charge even remains when extending the problem to SU(3) fermions. Additionally, identifying signatures for spinon and holon are found for the momentum-dependent spectral function in a magnetic field
