Quantum dynamics with ab initio potentials

This Special Topic issue on Quantum Dynamics with Ab Initio Potentials contains 53 contributions from the theoretical chemical physics community on new methods and applications of quantum mechanical characterization of dynamical processes using ab initio potential energy surfaces. These publications provide a snapshot of this vibrant field. Advances in quantum scattering theory are also represented in the collection. An important use of quantum dynamics calculations is the simulation of light–matter interactions that can be used to assign spectra in terms of quantum states and molecular motions, help interpret time-resolved spectra by providing a description for observed timescales, and predict and describe non-equilibrium phenomena initiated by light.
