Supplementary material to Heavy electrons and the symplectic symmetry of spin

Understand

This online material provides the technical detail for ``Heavy electrons and the symplectic symmetry of spin",(arXiv 0710.1122).

• Three parts.
• Part I - symplectic spins, their properties and gauge symmetries.
• Part II - derivation of two-chanel model for tetragonal heavy electron systems with the view to application to PuCoGa5 and NpPd_5Al_2, symplectic-N mean field theory and computation of NMR relaxation rate.
