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…
General spectral function expressions of a 1D correlated model
J. M. P. Carmelo, K. Penc
We introduce a method that allows the evaluation of general expressions for the spectral functions of the one-dimensional Hubbard model for all values of the on-site electronic rep…
One and Two-Electron Spectral Function Line Shapes in the Vicinity of the Upper-Hubbard Bands Lower Limit
J. M. P. Carmelo, L. M. Martelo, P. D. Sacramento
In this paper we derive general expressions for few-electron spectral functions of the one-dimensional Hubbard model for values of the excitation energy in the vicinity of the $M^{…
Description of the Energy Eigenstates of the 1D Hubbard Model in Terms of Rotated-Electron Site Distribution Configurations
J. M. P. Carmelo
In this paper we describe the pseudoparticles, holons, and spinons whose occupancy configurations describe the energy eigenstates of the one-dimensional (1D) Hubbard model in terms…
