摘要：

We calculate the low-temperature spectral function of one-dimensional incommensurate charge density wave states and half filled Mott insulators. At T = 0 there are two dispersing features associated with the spin and charge degrees of freedom, respectively. We show that already at very low temperatures ( compared to the gap) one of these features gets severely damped. We comment on implications of this result for photoemission experiments.
