treams.special.wignerd¶
- treams.special.wignerd(l, m, k, phi, theta, psi) = <ufunc 'wignerd'>¶
Wigner-D matrix element
\[D^l_{mk}(\varphi, \theta, \psi) = \mathrm e^{-\mathrm i m \varphi} d^l_{mk}(\theta) \mathrm e^{-\mathrm i k \psi}\]See also
treams.special.wignersmalld().Note
Mathematica uses a different sign convention, which means taking the negative angles.
- Parameters:
l (integer) – Degree \(l \geq 0\)
m (integer) – Order \(|m| \leq l\)
k (integer) – Order \(|k| \leq l\)
phi (float or complex) – Angles
theta (float or complex) – Angles
psi (float or complex) – Angles
- Returns:
complex
