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