Nature of problem:
Solve the evolution of open quantum systems of Hilbert space dimension N with self interactions and interaction with classical fields.
The SU(N) algebra is implemented as a C++ object and is embedded into the GSL ordinary differential equation solver.
The code is only implemented up to Hilbert spaces of dimension six, but a Mathematica notebook is provided in order to generate higher dimensional solutions. Furthermore, only ordinary differential equation solution methods that require only the first derivative can be used.
Proportional to the number of nodes, the dimension of the Hilbert space, the number of scalar functions, the number of density matrixes, and the numerical precision used in the problem.
