Effective mass of one 4He in liquid 3 He
A microscopic calculation of the effective mass of one 4He impurity in homogeneous liquid He 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 He atom and the particles in th...

| Resumo: | A microscopic calculation of the effective mass of one 4He impurity in homogeneous liquid He 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 He atom and the particles in the medium. The effective mass at equilibrium density, m; /m4 = 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 m: /m4. |
