Ferromagnetism and Transport in the Double-Exchange Model, with and without Phonons; Application to the Manganites
D. M. Edwards, A. C. M. Green
An introduction is given to the many-body coherent potential approximation (CPA) for the double-exchange (DE) model and the Holstein-DE model, the latter including coupling of the…
Uncertainties in the eta-Nucleon Scattering Length and Effective Range
A. M. Green, S. Wycech
The coupled eta-N, pi-N, gamma-N system is described by a K-matrix method. The parameters in this model are adjusted to get an optimal fit to pi-N --->pi- N, gamm…
Magnetism and Electronic States of Systems with Strong Hund Coupling
K. Kubo, D. M. Edwards, A. C. M. Green +2
This paper is a brief review of our recent studies concerning on magnetism and electronic states of lattice systems with Hund coupling. First we examined the effectiveness of the H…
Sum rules and 2-quark flux-tube structure
A. M. Green, P. S. Spencer, C. Michael
Sum rules -- relating the static quark potential V(R) to the spatial distribution of the action and energy in the colour fields of flux-tubes -- are applied in three ways: 1) To ex…
