The oscillatory thermalization scenario.
Real part of the lesser Green's function as a function of trel for various average times, (a) Falicov-Kimball, (b) Hubbard model; A grayscale is used with lighter shades indicating later average times. The inset in both cases shows the amplitude of G<(trel) as a function of average time. Panels (c) and (d) show for the FK and the Hubbard models respectively, the total energy (TE, green), the potential energy (PE, blue), kinetic energy (KE, red) and the current (black) as a function of time with the same parameters as in (a) and (b), respectively. The parameters are FK, E = 0.5, U = 0.5, T = 0.1. Hubbard, U = 4√3, E = (1,1,1)x4√3, T = √3.
