Abstract

The superfluid transition in homogeneous liquid He-3-He-4 mixtures isstudied numerically by restricted path integral Monte Carlo simulations. Finite-size scaling analysis of the results for the superfluid fraction yields values of the critical He-3 concentration in quantitativeagreement with experiment. The calculated single-particle kinetic energies of the two isotopes feature a clear, monotonic dependence on theHe-3 concentration.
