On the particle-hole symmetry of the fermionic spinless Hubbard model in D = 1

Thomaz, M.T.; Corrêa Silva, E.V.; Rojas, O. (Condensed Matter Physics, 2014)

We revisit the particle-hole symmetry of the one-dimensional (D=1) fermionic spinless Hubbard model, associating that symmetry to the invariance of the Helmholtz free energy of the one-dimensional spin-1/2 XXZ Heisenberg ...
The β-expansion of the D=1 fermionic spinless Hubbard model off the half-filling regime

Correa Silva, E.V.; Thomaz, M.T.; Rojas, O. (Condensed Matter Physics, 2015)

We obtain that when the spinless model is off the half-filling regime (μ ≠ V), the Helmholtz free energy (HFE) can be written as two β-expansions: one expansion comes from the half-filling configuration and another one ...
