Model calculation of orientational effect of deformed aerogel on the order parameter of superfluid 3He

Abstract

Theory of Rainer and Vuorio of small objects in superfluid ^3He is applied for calculation of the average orientational effect of a deformed aerogel on the order parameter of 3He. The minimum deformation which stabilizes the ordered state is evaluated both for specular and diffusive scattering of quasiparticles by the threads of aerogel.Comment: Contribution to QFS 2007, 6 pages, 1 figur
