Detailed Description

template<typename Kind, typename Scalar_ = double>
class Xped::Sym::SU2< Kind, Scalar_ >

Class for handling a SU(2) symmetry of a Hamiltonian without explicitly store the Clebsch-Gordon coefficients but with computing \((3n)j\)-symbols.

\describe_Scalar

Note: An implementation for the basic \((3n)j\) symbols is used from SU2Wrappers.h. Currently, the gsl-implementation and the wig3j/fastwig3j library can be used, but other libraries which calculates the symbols can be included. Just add a wrapper in SU2Wrappers.h.
