Longitudinal resonance and identification of the order parameter of the A-like phase of superfluid 3He in aerogel

TL;DR

This paper interprets recent experiments on longitudinal resonance in the A-like phase of superfluid 3He in aerogel, proposing a model based on the properties of a 'robust' order parameter.

Contribution

It introduces a theoretical interpretation of experimental results using a specific 'robust' order parameter model for superfluid 3He in aerogel.

Findings

Consistent explanation of longitudinal resonance data

Identification of the order parameter of the A-like phase

Insights into the superfluid's symmetry properties

Abstract

Interpretation of the recent experiments of V.V. Dmitriev et. al. on longitudinal resonance in the A-like phase, based on specific properties of "robust" order parameter is proposed.
