Two-spin irreducible spherical tensor operators.
Syntax
T=twospinist(spin_system,spin_a,spin_b,indices,type)
Arguments
spin_a - number of the first spin
spin_b - number of the second spin
indices - two-element vector [L,M] containing
rank and projection index; L=1,2 are
available
In Liouville space, type can be set to:
'left' - produces left side product superoperator 'right' - produces right side product superoperator 'comm' - produces commutation superoperator (default) 'acomm' - produces anticommutation superoperator
In Hilbert space calculations, the type parameter is ignored, and the operator itself is always returned.
Outputs
T - irreducible spherical tensor operator
