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 SjoK lander (STLS) to study a model two-component fermion}boson system (He}He mixture) in two dimensions. We calculate the partial static structure factors and e!ective potentials, given a model bare interaction with hard-core plus an attractive tail. We study the dependence of these quantities on the He fraction in the mixture. Collective modes for the mixture are also discussed.
