sd-type Exchange Interactions in Nonhomogeneous Ferromagnets
W. N. G. Hitchon, G. J. Parker, A. Rebei
Motivated by a need to understand spin-momentum transport in CPP (current perpendicular to the plane) structures, a quantum field theoretical treatment of spin-spin interactions in…
Spin accumulation in ferromagnets
W. N. G. Hitchon, R. W. Chantrell, A. Rebei
Using a density matrix formulation for the effective action, we obtain a set of macroscopic equations that describe spin accumulation in a non-homogeneous ferromagnet. We give a ne…
Generalized Random Phase Approximation: Zero and Non-Zero Temperature Properties of an Interacting Electron Gas
A. Rebei, W. N. G. Hitchon
Correlated systems at both zero and nonzero temperature are treated here from a novel angle using a functional method. This functional method is an extension of the usual effective…
The Specific Heat of a Fermi Gas at Low Temperature: A closer look at the TlnT behavior
A. Rebei, W. N. G. Hitchon
At finite temperature, a Fermi gas can have sates that hold simultaneously a particle and a hole with a finite probability. This gives rise to a new set of diagrams that are absent…
