摘要：

High resolution valence photoemission spectra from quasi-one-dimensional metals cannot be explained in the one-particle picture. Correlation effects can be exactly included within the Tomonaga-Luttinger model. We present analytical and numerical results for the spectral functions for the model at zero and finite temperatures, which show drastic many-body effects.
