Particles with short-range interactions and a large scattering length have universal low-
energy properties that do not depend on the details of their structure or their interactions at …

Herein, recent experiments on the spectroscopy and chemical reactions of molecules and
complexes embedded in helium droplets are reviewed. In the droplets, a high spectroscopic …

Standard density functional approximations cannot accurately describe interactions between
nonoverlapping densities. A simple remedy consists in correcting for the missing interactions …

Magnetically tunable Feshbach resonances were employed to associate cold diatomic
molecules in a series of experiments involving both atomic Bose and two-spin-component …

Important progress has been made in the construction of globally analytic potential energy
surfaces of, in particular, small molecules using ab initio quantum chemistry data in recent …

The adiabatic, relativistic, and quantum electrodynamics (QED) contributions to the pair
potential of helium were computed, fitted separately, and applied, together with the …

The quantum mechanical three-body problem is studied for general short-range interactions.
We work in coordinate space to facilitate accurate computations of weakly bound and …

Shear viscosity is a measure of the amount of dissipation in a simple fluid. In kinetic theory
shear viscosity is related to the rate of momentum transport by quasi-particles, and the …

The interatomic potentials between members of the rare gas family of atoms provide the
largest class of chemically identical atoms which interact via van der Waals potentials. 1, 2 …

▪ 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 …
