Central transition operator for half-integer spins expressed in the Pauli basis.
Syntax
A = centrans(mult,type)
Arguments
mult - multiplicity of the spin (even positive integer)
type - operator type: 'x' for Sx, 'y' for Sy,
'z' for Sz, '+' for raising, '-' for lowering
Outputs
A - sparse matrix of the central transition operator
Examples
A central transition raising operator for a spin-3/2 system:
A = centrans(4,'+');
Notes
The operator is returned as a complex sparse matrix.
