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 …

This review deals with the relation between intermolecular potentials and the spectra of van
der Waals molecules. Intermolecular potentials cannot be measured directly, but the …

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

The J= 0 many-body Schrödinger equation for He N 4 clusters with N= 3–10 is solved
numerically by combining Monte Carlo methods with the adiabatic hyperspherical …

Helium shows fascinating quantum phenomena unseen in any other element. In its liquid
phase, it is the only known superfluid. The smallest aggregates of helium, the dimer (He2) …

The 4 He 3 system is investigated using a hard-core version of the Faddeev differential
equations. Realistic 4 He-4 He interactions are employed, among them the LM2M2 potential …

Recent advances in controlling interatomic interactions, coupled with new techniques for
producing and interrogating exotic regimes in ultracold quantum gases, have resulted in the …

Helium trimer bound states are calculated by means of a variational method described in
terms of atom pair coordinates and distributed Gaussian basis functions for zero total …

We calculate the L= 0 ground and excited state energies for the rare gas trimers He 3, Ne 3,
and Ar 3. An adiabatic representation is adopted to solve the nuclear Schrödinger equation …

A variational wave function constructed with correlated hyperspherical harmonic functions is
used to describe the Helium trimer. This system is known to have a deep bound state. In …
