Path integral Monte Carlo study of SF6-doped helium clusters

The path-integral Monte Carlo technique is applied to study the SF6He39 cluster at low temperatures. The method employs as input only pair potentials, the number of atoms, and the temperature, and is thus independent of the trial function bias which can affect calculation of structural quantities in variational and diffusion Monte Carlo. We thereby obtain an unambiguous answer to the question o...

Path-integral Monte Carlo simulation of helium at negative pressures

Path-integral Monte Carlo simulations of liquid helium at negative pressure have been carried out for a temperature range from the critical temperature to below the superfluid transition. We have calculated the temperature dependence of the spinodal line as well as the pressure dependence of the isothermal sound velocity in the region of the spinodal. We discuss the slope of the superfluid tran...

Path integral Monte Carlo study of 4He clusters doped with alkali and alkali-earth ions.

Path integral Monte Carlo calculations of (4)He nanodroplets doped with alkali (Na(+), K(+) and Cs(+)) and alkali-earth (Be(+) and Mg(+)) ions are presented. We study the system at T = 1 K and between 14 and 128 (4)He atoms. For all studied systems, we find that the ion is well localized at the center of the droplet with the formation of a "snowball" of well-defined shells of localized (4)He at...

Two-dimensional H2 clusters: A path-integral Monte Carlo study

The possibility of maintaining H2 in a fluid state at temperatures low enough to produce a superfluid has recently attracted considerable attention. Unfortunately, the H2-H2 interaction is too strong to allow molecular hydrogen to be a liquid below its bulk triple point of 14 K. One way to attain a liquid ground state is to reduce the effective attraction between the H2 molecule or alternativel...

Permutation sampling in Path Integral Monte Carlo

Abstract A simple algorithm is described to sample permutations of identical particles in Path Integral Monte Carlo (PIMC) simulations of continuum many-body systems. The sampling strategy illustrated here is fairly general, and can be easily incorporated in any PIMC implementation based on the staging algorithm. Although it is similar in spirit to an existing prescription, it differs from it i...
