Deut pair.m

All possible states of a spin-1 pair, classified by the total spin into singlet, triplet, and quartet.

Syntax

    [S,T,Q,Tc,Qc]=deut_pair(spin_system,spin_a,spin_b,options)

Arguments

   spin_a  - the number of the first spin

   spin_b  - the number of the second spin

   options.dephasing - set to 1 to eliminate the states that are
                       not stationary under Az+Bz Hamiltonian,
                       the default is to keep everything

Outputs

   S       - singet state density matrix (Hilbert space)
             or state vector (Liouville space)

   T       - triplet state density matrices (Hilbert space)
             or state vectors (Liouville space), ordered in
             a cell array as {T+,T0,T-}

   Q       - quintet state density matrices (Hilbert space)
             or state vectors (Liouville space), ordered in
             a cell array as {Q++,Q+,Q0,Q-,Q--}

Notes

WARNING: the states above are NOT irreducible spherical tensors - Bargon just kroneckered up some Zeeman states and gave them what looked to him like appropriate labels.
