Abstract

The ground state of homogeneous, supefluid - He-4-normal-He-3 mixtures is studied by Fixed-Node Diffusion Monte Carlo simulations. The condensate fraction of the He-4 component only depends on the He-3 concentration through its effect on the average density. Slight deviations ofthe structural properties from previous variational results, obtainedwithin the Average Correlation Approximation (ACA), are discussed. The momentum distribution and effective mass of the Fermi (He-3) component are also calculated.
