Rotating Wave Approximation in propagators has to be used transparently #100

Closed tmancal74 closed 1 year ago

tmancal74 commented 5 years ago

Current implementation of the propagators does not give use any control over the use of RWA. We need to implement switches to allow the user to prevent RWA, or enable output of the propagated density matrix in RWA. The default behavior should be that RWA is used if Hamiltonian contains information about the right RWA frequencies, but the calculated density matrix should be outputted including the fast frequencies.

RWA is now used when the Hamiltonian has RWA. Methods to convert density matrix and evolution superoperator from and to RWA are implemented. With this, the issue can be closed.
