template<std::size_t N, typename Scalar>
class Sym::SUN< N, Scalar >
Class for handling a SU(N) symmetry of a Hamiltonian with explicitly storage the Clebsch-Gordon coefficients.
- Template Parameters
-
| Scalar | : double or complex<double> |
| N | : the N in SU(N) |
- Warning
- Use the the external CGC-Library: https://homepages.physik.uni-muenchen.de/~vondelft/Papers/ClebschGordan/
- Longterm Todo:
- To use general SU(N) symmetries, several adjustions are necessary in the code, concerning the innermultiplicity.
