Splitting of the superfluid transition in ${}^3$He by nematic aerogels

Abstract

Role of inhomogeneous perturbations of nematic aerogel on the form of the order parameter emerging at the transition of liquid ${}^3$He in the superfluid state is considered. It is shown that a region of stability of the polar distorted ABM phase can begin right from the transition temperature. The symmetry argument is given, which selects the most favorable aerogel for stabilization of pure polar phase.
