Path Integral Hybrid Monte Carlo Study on Structure of Small Helium-4 Clusters Doped with a Linear Molecule

Article

Abstract

Microscopic structure of small helium-4 clusters doped with a carbonyl sulfide molecule, OCS(4He)N, at 0.37 K is studied by the path integral hybrid Monte Carlo method; the size of the cluster N ranges from N=2 to N=5. In all the cases examined in the present study, the helium atoms are localized around the carbon atom of the OCS molecule, forming a doughnut-type structure around the molecular axis. Bosonic exchange among the helium atoms is found to be promoted in the doughnut region, showing an anisotropic “superfluid” response of the clusters.
