Analytical Results for the Grand-Canonical Partition Function for Unidimensional Hubbard Model up to Order ${\beta }^5$

I. C. Charret, E. V. Correa Silva, S. M. de Souza +1

We calculate the exact analytical coefficients of the $\beta$ expansion of the grand-canonical partition function of the unidimensional Hubbard model up to order ${\beta }^5$, using an altern…
