WavePacket
Dynamics of quantum systems, controlled by external fields
...Optionally accounting for the interaction with external electric fields within the semiclassical dipole approximation, WavePacket can be used to simulate modern experiments involving ultrashort light pulses in photo-induced physics or chemistry, including quantum optimal control. With its visualization of quantum dynamics generated 'on the fly', WavePacket is suitable for teaching quantum mechanics as well as for research projects, see also the numerous demonstration examples .
While the Matlab/Octave version is already in a mature state, the C++/Python version is still under construction. Using tensor train techniques, the additional WaveTrain package aims at beating the curse of dimensionality.
