qimpy.math.spherical_harmonics.get_harmonics_tilde_and_prime
- get_harmonics_tilde_and_prime(l_max, G, compute_prime=True)
Same as
get_harmonics_and_prime()
, but in reciprocal space. The result contains an extra phase of \((iG)^l\), as discussed in get_harmonics_tilde.- Parameters:
l_max (int) –
G (Tensor) –
- Return type:
tuple[Tensor, Tensor]
