Abstract

The ground-state properties of helium clusters 4HeN and 4HeN3He, for N≤ 40, adsorbed on the surface of cesium are studied using variational and diffusion Monte Carlo calculations. Binding properties are determined using two different Cs–He interaction potentials. For the smallest clusters, self-binding on a Cs surface is stronger than in two or three dimensions. For N > 10 self-binding in three dimensions is stronger than on Cs for both types of Cs–He interaction potential considered. The obtained binding energies and structure are compared to results of recent density functional calculations. The emergence of edge states of 3He atom, localized along the contact line of 4He cluster with a cesium surface, is studied. First indication that 3He atom prefers to be close to the contact line appears already for the 4He33He cluster.
