Finite temperature spectral function of Mott insulators and charge density wave states.
Phys Rev Lett 90:12 (2003) 126401
Abstract:
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.Dynamical structure factor of the anisotropic Heisenberg chain in a transverse field
