Abstract
A microscopic calculation of the effective mass of one impurity in homogeneous liquid at zero temperature is performed for an extended Jastrow-Slater wave function, including two- and three-body dynamical correlations and also backflow correlations between the atom and the particles in the medium. The effective mass at equilibrium density, m〈main/=1.21, is in very good agreement with the recent experimental determination by Edwards et al. The three-particle correlations appear to give a small contribution to the effective mass and different approximations for the three-particle distribution function give almost identical results for /.
