Abstract

A variational procedure, introduced recently to study superconductivity, is extended to account for the properties of interacting electrons in normal metals. Each independent-electron band is found to split into two correlated-electron bands. Excellent agreement is achieved in the thermodynamic limit for the one-dimensional Hubbard model. This analysis is furthermore shown to apply for any space dimension and temperature. The relevance of the Hubbard Hamiltonian to all three-dimensional superconductors is vindicated. The t-J model is reviewed. An electron paramagnetic resonance (EPR) experiment is proposed to check the validity of this analysis.
