Cooper pairing with the onsite exchange interaction: A possible mechanism of high-temperature superconductivity
Jacques R. Eone
The paper proposes that the onsite exchange (Hund's) interaction in a Hubbard model can provide an attractive component to the otherwise repulsive Coulomb interaction, leading to C…
Tight-binding model: correction of the d-band approximation
Jacques R. Eone
The electronic structure, when restricted to the d-band approximation, is a computational model that is both efficient and useful for describing transition metals. In the absence o…
A magnetic tight-binding model: surface properties of transition metals and cobalt nanoparticles
Jacques R. Eone
The magnetic and surface properties of some transition metals have been investigated within the tight-binding approximation, including Coulomb correlations. These surface propertie…
A magnetic tight-binding model: correlations in ferromagnetic transition metals
Jacques R. Eone
Correlations derived through single-particle approximations of the many-body problem frequently result in erroneously inflated or diminished physical properties. In the context of…
