In this rich landscape of molecular processes and systems, the field of quantum molecular dynamics has sparkled in recent years . Great progress has been achieved at the more fundamental, theoretical level as well as from the point of view of the algorithms/software developments and applications. Many novel ideas have been proposed, motivated by the challenges encountered when simulating complex organic materials and biological systems , or when investigating phenomena over long time scales to look at slow processes such as fluorescence or vibrational relaxation, or when creating hybrid light-matter states in the strong coupling regime in optical and plasmonic microcavities .
