Large amplitude vibrational motion of fullerenes — •Jan Handt and Rüdiger Schmidt — Institut für Theoretische Physik, Technische Universität Dresden, D-01062 Dresden, Germany
In the optical laser regime two-colour pump-probe experiments in combination with nonadiabatic molecular dynamics calculations have revealed the excitation of a giant breathing motion in C60 [1]. Further theoretical studies showed the strong orientation dependence of energy absorption and subsequent relaxation dynamics leading to large amplitude vibrational motion up to symmetric fission processes [2]. Here, we extend these calculations and investigate large collective nuclear excitations in fullerenes up to the XUV laser regime which is now feasible by FEL sources, using nonadiabatic quantum molecular dynamics methods (NA-QMD(-H)) [3].
