Effective Mass of One 4he Atom in Liquid 3he

凝聚态物理 2009-10-22 v1

摘要

A microscopic calculation of the effective mass of one 4^4He impurity in homogeneous liquid 3^3He 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 4^4He atom and the particles in the medium. The effective mass at saturation density, m4/m4=1.21m_4^*/m_4=1.21, is in very good agreement with the recent experimental determination by Edwards {\it 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 m4/m4m_4^*/m_4.
