Superfluidity in a Doped Helium Droplet
arXiv:cond-mat/0208088 · doi:10.1103/PhysRevLett.90.065301
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.
