Abstract

The spectral functions of tJ and tJ_XY models in the limit of J/t-> 0 and at finite temperatures T>>t are calculated using the spin-charge factorized wave function. We find that the Luttinger-liquid like scaling behavior for a finite system with L sites is restricted below temperatures of the order T = J/L. We also observe weight redistribution in the photoemission spectral function in the energy range t, which is much larger than the temperature.
