Hubbard-model description of the high-energy spin-spectral-weight distribution in La(2)CuO(4)
J. M. P. Carmelo, M. A. N. Araujo, S. R. White +1
The spectral-weight distribution in recent neutron scattering experiments on the parent compound LaCuO (LCO), which are limited in energy range to about 450\,meV, is studie…
Spin-spectral-weight distribution and energy range of the parent compound LaCuO
M. A. N. Araujo, J. M. P. Carmelo, M. J. Sampaio +1
The spectral-weight distribution in recent neutron scattering experiments on the parent compound LaCuO (LCO), which are limited in energy range to about 450\,meV, is studie…
A description of the Hubbard model on a square lattice consistent with its global symmetry
J. M. P. Carmelo, M. J. Sampaio
In this paper a description of the Hubbard model on the square lattice with nearest-neighbor transfer integral , on-site repulsion , and sites consistent with it…
Global symmetry of the Hubbard model on bipartite lattices
J. M. P. Carmelo, Stellan Ostlund, M. J. Sampaio
It is found that for on-site interaction the local gauge symmetry of the Hubbard model on a bipartite lattice with vanishing transfer inte…
