Nuclear dynamics in quantum clusters

We address recent developments in the exploration of quantum nuclear dynamics in large, finite, low-temperature systems, focusing on Bose–Einstein condensates (T≃100 nK), optical molasses (T≃10–100 μK) and aromatic molecule·Hen clusters (T 
= 0.4 K). The expansion of optical molasses bears a close analogy to the nuclear dynamics of Coulomb explosion of multicharged clusters. Spectroscopy of electronic–vibrational excitations of anthracene·Hen 
 clusters manifests large nuclear quantum effects, nonrigidity, large scale confinement and permutational symmetry effects. Perspectives for the novel research 
 area of nuclear dynamics of ultracold finite systems are advanced.
