N. Nakamura et Y. Suzumura, COMMENT ON DENSITY-OF-STATES OF TOMONAGA-LUTTINGER MODEL AT FINITE TEMPERATURES, Progress of theoretical physics, 97(1), 1997, pp. 163-167
By use of the single particle Green's function of the Tomonaga-Lutting
er model at finite temperature, the density of states around the Fermi
energy is calculated to examine the range of temperatures in which pr
operties of the Luttinger liquid are found.
