Model two-dimensional liquid 3He-4He mixture within the self-consistent field approximation

Abstract

In this paper we use the self-consistent scheme proposed by Singwi, Tosi, Land and Sjölander (STLS) to study a model two-component fermion - boson system (3He-4He mixture) in two dimensions. We calculate the partial static structure factors and effective potentials, given a model bare interaction with hard-core plus an attractive tail. We study the dependence of these quantities on the 3He fraction in the mixture. Collective modes for the mixture are also discussed. © 1999 Elsevier Science B.V. All rights reserved.
