Analytical Results of the One-Dimensional Hubbard Model in the High Temperature Limit
I. C. Charret, E. V. Correa Silva, S. M. de Souza +3
We investigate the grand potential of the one-dimensional Hubbard model in the high temperature limit, calculating the coefficients of the high temperature expansion (-expansion…
Free Fermions at Finite Temperature: An Application of the Non-Commutative Algebra
S. M. de Souza, O. Rojas Santos, M. T. Thomaz
Charret et. al. applied the properties of the Grassmann generators to develop a new method to calculate the coefficients of the high temperature expansion of the grand canonical pa…
Grassmann Algebra and Fermions at Finite Temperature
I. C. Charret, E. V. Corrêa Silva, S. M. de Souza +2
For any d-dimensional self-interacting fermionic model, all coefficients in the high-temperature expansion of its grand canonical partition function can be put in terms of multivar…
