bos2ist.m

Irreducible spherical tensor expansion of a user-specified bosonic operator product.

Syntax

[states,coeffs]=bos2ist(prod_spec,nlevels)

Parameters

prod_spec - bosonic operator product specification

                    in which 'C' stands for creation opera-
                    tor and 'A' for annihilation operator,
                    for example 'CCAA'
        nlevels   - number of energy levels in the trunca-
                    ted bosonic mode

Outputs

states - states, in the Spinach IST basis index-

                  ing, that contribute to the operator in
                  question; use lin2lm to convert to L,M
                  spherical tensor indices
        coeffs  - coefficients with which the ISTs enter
                  the linear combination
