Ci. Um et al., AN EXTENDED VARIATIONAL JASTROW THEORY FOR A 2-DIMENSIONAL HE-3-HE-4 MIXTURE, Journal of the Korean Physical Society, 33(4), 1998, pp. 455-461
Using a variational Jastrow wavefunction extended to a three-body corr
elation function, a hypernetted chain, and a Fermi hypernetted chain s
cheme with the contributions of elementary diagrams, we have investiga
ted the ground-state properties, such as the energy per particle and t
he structural properties, of a two-dimensional He-3-He-4 mixture. We h
ave shown that the ground-state energies increase as a function of the
impurity concentration. We have also evaluated the shifts of the ener
gies coming from statistics in comparison with boson He-3-He-4 mixture
