enlev2bm.m

Bosonic monomial expansion of specific bosonic energy

Syntax

          [states,coeffs]=enlev2bm(nlevels,lvl_num)

Arguments

        nlevels - number of energy levels in the  mode,
                  a positive integer
        lvl_num - energy level number, counting from the
                  empty mode state upwards

Outputs

        states  - states, in the Spinach BM basis index-
                  ing, that contribute to the operator in
                  question; use lin2kq to convert to K,Q
                  bosonic monomial indices
        coeffs  - coefficients with which the BMs enter
                  the linear combination
