We calculate the photoemission spectral function of the one-dimensionalHubbard model away from half filling using the dynamical density matrixrenormalization group method. An approach for calculating momentum-dependentquantities in finite open chains is presented. Comparison with exact BetheAnsatz results demonstrates the unprecedented accuracy of our method. Ourresults show that the photoemission spectrum of the quasi-one-dimensionalconductor TTF-TCNQ provides evidence for spin-charge separation on the scale ofthe conduction band width.Comment: REVTEX, 4 pages including 4 EPS figures (changed); correct chemical  potential used to define excitation energies in figures and tex
