Superfluid phases of 3He in aerogel

TL;DR

This paper derives a criterion for selecting superfluid phases of 3He in aerogel, revealing differences in the order parameter behavior under magnetic fields compared to pure 3He, with potential observable effects.

Contribution

It provides a formal derivation of the phase selection criterion for superfluid 3He in aerogel, highlighting differences from pure 3He.

Findings

Variation of the B-like phase order parameter in magnetic field differs from pure 3He.

Possible observable consequences of the phase differences are discussed.

Abstract

Formal derivation of criterion for selection of superfluid phases of 3He in aerogel is presented. At the strength of the derived criterion variation of the order parameter of B-like phase in magnetic field differs from that of B-phase of pure 3He. Possible observable consequences of this difference is discussed.
