Quantum dynamics in the conical intersection To assist in the analysis of the quantum dynamics in internal conversion (IC) processes a number of papers have been presented which analyse the process in terms of perturbation theory, in terms of effective modes and quadratic coupling, careful analysis of the geometric phase effects near the CIX, or propose simple models to bring in a clearer picture of the fundamentals of the process.
