Complex Electronic Behavior in a 1D Correlated Quantum Liquid
J. M. P. Carmelo
The relation of the rotated-electron site distribution configurations that describe the energy eigenstates of the one-dimensional Hubbard model to the momentum occupancy configurat…

Correlation-function asymptotic expansions: pre-factors universality
J. M. P. Carmelo, K. Penc
We show that the pre-factors of all terms of the one-dimensional Hubbard model correlation-function asymptotic expansions have an universal form, as the corresponding critical expo…

Wave-Function Factorization of the Normal-Ordered 1D Hubbard Model for Finite Values of the On-site Repulsion U
J. M. P. Carmelo
In this paper we find that in the thermodynamic limit and for the the ground-state normal-ordered 1D Hubbard model the wave function of the excited energy eigenstates which span th…
