Research output: Contribution to journalArticlepeer-review


A microscopic path-integral Monte Carlo (PIMC) estimator of the local contribution to the total superfluid response is presented. Simulations of 4He droplets containing linear (HCN)3 isomers show a significant reduction in the superfluid response of the first solvation. Furthermore, this reduction is shown to be due in part to thermal excitations, in addition to the temperature-independent normal fluid assumed to be induced by the anisotropic HCN-helium interaction potential.
