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^{…
The Hubbard model description of the photoemission TCNQ singular features
J. M. P. Carmelo, K. Penc, P. D. Sacramento +2
In this paper we use the pseudofermion dynamical theory (PDT) in the study of the one-electron removal singular spectral features the one-dimensional Hubbard model. The PDT reveals…
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…
Normal-Ordered Wave-Function Factorization of the 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 excited states contained in few-electron exc…
Electronic structure of the quasi-one-dimensional organic conductor TTF-TCNQ
M. Sing, U. Schwingenschlögl, R. Claessen +6
We study the electronic structure of the quasi-one-dimensional organic conductor TTF-TCNQ by means of density-functional band theory, Hubbard model calculations, and angle-resolved…
