Time-dependent simulation of open and closed quantum systems
WavePacket is a program package for numerical simulation of quantum-mechanical wavepacket dynamics for distinguishable particles. It can be used to solve one or more (i.e. coupled channels) time-independent or time-dependent (linear) Schrödinger and Liouville-von Neumann-equations. Optionally accounting for the interaction with external electric fields within the semiclassical dipole approximation, WavePacket can simulate modern experiments using ultrashort light pulses in photo-induced physics or chemistry. WavePacket is especially suitable for teaching of quantum mechanics as well as for research projects in physics, chemistry, and scientific computing. The present C++ version is an object-oriented rewrite of the existing Matlab version aiming to be more flexible. In particular, the goals are easy handling of open and closed systems and support for unusual setups.
ACCORD is a C library for composition of scanning electron or helium-ion microscope images with correction of drift. It produces significantly more accurate images than the traditional imaging techniques and also provides drift trajectories.
