Superfluidity in a Doped Helium Droplet
E. W. Draeger, D. M. Ceperley
Abstract
Path Integral Monte Carlo calculations of the superfluid density throughout 4He droplets doped with linear impurities (HCN)n are presented. After deriving a local estimator for the superfluid density distribution, we find a decreased superfluid response in the first solvation layer. This effective normal fluid exhibits temperature dependence similar to that of a two-dimensional helium system.
