Theoretical study on the structure of Na+-doped helium clusters: Path integral Monte Carlo calculations

Abstract

The microscopic structure of Na+-doped helium clusters was investigated using the path integral Monte Carlo (PIMC) method. In particular, the nature of superfluidity in these clusters was studied by examining the temperature and size dependences of several physical quantities such as energy and superfluid fraction. Results with Boltzmann statistics were compared to clarify the effects of superfluidity.
