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 …

Faddeev-Yakubovski equations are solved numerically for He 4 tetramer and trimer states
using realistic helium-helium interaction models. We describe the properties of ground and …

We report variational calculations of energies of 3 He N droplets (20≤ N≤ 40), using Aziz
atom-atom interactions. The trial wave function has a simple structure, combining two-and …

The Faddeev differential equations for a system of three particles with a hard-core
interaction are described. Numerical results on the binding energies of the 4 He 3 and 3 He …

The ground-state energies and the radial and pair distribution functions of neutral He 4
clusters are systematically calculated by the diffusion Monte Carlo method in steps of one …

The stability of drops made of 3 He atoms is studied by means of a Monte Carlo variational
method using wave functions with good angular momentum quantum numbers. The number …

We have studied the stability of mixed 3He= 4He clusters in L 0 states by the diffusion Monte
Carlo method, employing the Tang-Toennies-Yiu He-He potential. The clusters 3He4HeN …

A stability chart of mixed 4 He and 3 He clusters has been obtained by means of the
diffusion Monte Carlo method, using both the Aziz HFD-B and the Tang-Toennies-Yiu atom …

The existence of small helium clusters containing a variable number of H 4 e and H 3 e
atoms is studied within a variational Monte Carlo calculation employing the Aziz HFD-B (HE) …

The ground-state properties of 3 He and 4 He trimers and tetramers in infinite and restricted
two-dimensional and quasi-two-dimensional (2D) space are studied. Using Monte Carlo …
