An Introduction to Classical Description of Nonadiabatic Quantum Dynamics

Stefan Dilthey, Mark Santer, Michael Thoss, Gerhard Stock




Probability density. Top: QM; Bottom: QC Development of time-dependent semiclassical and mixed quantum-classical methods for the description of ultrafast nonadiabatic dynamics. We are interested in fundamental aspects of semiclassical dynamics as well as in the development of practical mixed quantum-classical techniques which are capable of describing the dynamics of complex molecular systems.

In the next picture are shown two orbits of period 1 which contribute to the system: Orbits with period 1

These both peiodic orbits are enough to describe the diabatic population almost quantitatively as shown here: Contribution of orbits with period 1 to the diabatic population
