Path integral Monte Carlo simulation of isotopic liquid helium mixtures

Research output: Contribution to journal › Article › peer-review

Abstract

We report results of a path integral Monte Carlo simulation of a liquid ³He-⁴He mixture at low temperature. In the limit of low ³He concentration, a kinetic energy of 17 K is found for the ³He atoms; the ³He effective mass is m* = 2.3m. The restricted path integral Monte Carlo method was utilized to investigate the separation of the mixture into a ³He- and ⁴He-rich phase.
