One-Electron Singular Branch Lines of the Hubbard Chain
J. M. P. Carmelo, K. Penc, L. M. Martelo +5
The momentum and energy dependence of the weight distribution in the vicinity of the one-electron spectral-function singular branch lines of the 1D Hubbard model is studied for all…

Superconductivity Driven by Chain Coupling and Electronic Correlations
J. M. P. Carmelo, F. Guinea, K. Penc +1
We present an analysis of a system of weakly coupled Hubbard chains based on combining an exact study of spectral functions of the uncoupled chain system with a renormalization gro…
