▪ Abstract Laser ablation of in situ metals has recently made it possible to immerse a large
number of different metal atoms and ions and small clusters of metal atoms in liquid helium …

We review the physics of helium nanodroplets with emphasis on theoretical aspects that
have been the subject of recent research, like 3 He and mixed 3 He− 4 He droplets, vortices …

Using a finite-range density functional, we have investigated the energetics and structural
features of mixed helium clusters. The possibility of do** the cluster with a molecule of …

The classical integral cross sections of large superfluid 4 He N droplets and the number of
atoms in the droplets (N= 10 3− 10 4) have been measured in molecular beam scattering …

Recent experiments on the electronic spectroscopy of atoms, clusters, and organic
molecules embedded in helium nanodroplets are reviewed. Electronic transitions imply a …

This book is devoted to the description of Bosonic and Fermionic systems: metallic clusters;
quantum dots, wires, rings and molecules; trapped Fermi and Bose atoms; liquid drops of …

We show that, at high densities, fully variational solutions of solidlike types can be obtained
from a density functional formalism originally designed for liquid He 4. Motivated by this …

The dynamics resulting from electronic excitations of helium clusters were explored using ab
initio molecular dynamics. The simulations were performed with configuration interaction …

Helium nanodroplets and trapped Bose-Einstein condensates in dilute atomic gases offer
complementary views of fundamental aspects of quantum many-body systems. We discuss …

We have measured the laser-induced fluorescence excitation spectra of the 3 1 P 1 0← 3 1
S 0 transition of Mg atoms solvated in helium nanodroplets. The observed blue shifts and …
