Hamiltonian (...)In the <strong>in</strong>terstitial region we don’t have sp<strong>in</strong>-orbit,Hamiltonian is a sum of only k<strong>in</strong>etic energy and effective potentials:Ĥ = − 22m ∇2 + ˆV ,where ˆV comb<strong>in</strong>es V eff and B eff <strong>in</strong> a form of 2x2 potential matrix.In the spheres w can have everyth<strong>in</strong>gThus, Hamiltonian is more complicated:Ĥ = − 22m ∇2 + ˆV + Ĥ so + Ĥ orb + Ĥ cAs a result, there are same choices:wien workshop 2003 – p.20/40
