AB  - Recent experimental developments in the creation and diagnostic probing of metallic nanoclusters has made it
AB  - possible to explore their interaction with electromagnetic radiation, thus revealing information on their electronic
AB  - properties. Free electrons inside such clusters occupy a very small volume so their characteristics may
AB  - exhibit significant differences to bulk matter in a similar thermodynamic state. Using high-resolution molecular
AB  - dynamics simulation, we study electronic correlations of laser-excited, sodium-like nanoclusters. To cover a
AB  - broad range from nano- to microscale, the momentum autocorrelation function is evaluated for systems ranging
AB  - from 150 to more than half a million electrons. The Coulomb force computation is accelerated by utilizing the
AB  - parallel Barnes-Hut tree code PEPC. Complex electronic resonances are found for finite-sized clusters which
AB  - do not appear in bulk systems. Analysis of these oscillation modes with a new diagnostic technique show that
AB  - these are located in different spatial regions within the clusters.
