qimpy.math.spherical_harmonics

Calculate spherical harmonics and their product expansions.

Module Attributes

L_MAX	Maximum l for calculation of harmonics
L_MAX_HLF	Maximum l of harmonics in products

Functions

get_harmonics	Compute real solid harmonics \(r^l Y_{lm}(r)\) for each l <= l_max.
get_harmonics_and_prime	Compute real solid harmonics \(r^l Y_{lm}(r)\) for each l <= l_max.
get_harmonics_tilde	Same as get_harmonics(), but in reciprocal space.
get_harmonics_tilde_and_prime	Same as get_harmonics_and_prime(), but in reciprocal space.
