Abstract:

The high temperature series of the thermodynamic potential and the uniform susceptibility have been investigated for the single-band Hubbard model in the strong correlation limit. It is rigorously shown that the series absolutely converge both in the low density and the half-filled limit. Correct first terms have been obtained up to the ninth order in terms of the inverse temperature. Coefficients of the series are oscillating rapidly as functions of the occupation probability of electrons.
