A more accurate solution of the model (of an 8-band of interacting electrons) discussed in
paper I is obtained. The new solution predicts a finite lifetime for the pseudo-particles and also …

… In a previous paper (Hubbard 1963; hereinafter this paper will be referred to as I) a
theory of correlation effects in narrow s-bands was developed. This theory was restricted to s-bands …

It should be noted that vij k~= vk $ ij necessar-ily, so that V can be regarded as a quadratic
form in the variables $ f&= qf q&. Bringing this quadratic form into normal form one has V=+ …

… In a previous paper (Hubbard 1957), which will be referred to as I, a method * analyzing the
perturbation series for the many-body problem was described, wliie it was stated, would lead …

It is pointed out that one of the main effects of correlation phenomena in d- and f-bands is to
give rise to behaviour characteristic of the atomic or Heitler-London model. To investigate …

The purpose of this paper is to explore the role of emotional functioning in the social competence
of children, with a particular focus on children's peer relations. Literature on children's …

A self-consistent, kinetic theory of ion-solvent interactions is developed within the framework
of continuum mechanics. It is shown that the hydrodynamic coupling between viscous …
