WavePacket 5.0: A Matlab program package for quantum-mechanical wavepacket propagation and time-dependent spectroscopy

Abstract

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 equations. Optionally accounting for the interaction with external electric fields (semiclassical dipole approximation), WavePacket can simulate modern experiments using ultrashort laser pulses. Thus it can be used as a flexible tool for many simulation tasks in photoinduced physics, chemistry, and in related fields. The extended graphical capabilities allow visualization of wavepacket dynamics 'on the fly', including Wigner transforms to phase space. WavePacket is especially suitable for teaching of quantum mechanics in physics, chemistry, and scientific computing.
