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.
