Structure coefficient tables for the associative envelopes of
truncated Weyl algebras spanned by orthogonalised bosonic mo-
nomials.
Syntax
[product_table_left,product_table_right]=bos_product_table(nlevels)
Arguments
nlevels - number of bosonic ladder population levels
The output contains the structure coefficients in the follow- ing lowing conventions:
B{n}*B{m}=...+product_table_left(n,m,k)*B{k}+...
B{m}*B{n}=...+product_table_right(n,m,k)*B{k}+...
corresponding to the expansion of the left and the right mul-
tiplicative action by B{n} on B{m} as given in Eq 7.18 of the
first edition of IK's book (normalisation is missing in the
book, that's a typo).
Note: these are expensive tables, a disk cache is created and
used automatically.
