Dissipation of the 3^He A-B Transition

TL;DR

This paper develops a comprehensive hydrodynamic theory for the 3He A-B phase transition, emphasizing the importance of previously overlooked dissipative processes at low interface velocities.

Contribution

It introduces a rigorous hydrodynamic framework that includes all dissipative processes, highlighting the significance of hydrodynamic length scale effects.

Findings

Dissipative processes dominate at low interface velocities.

Hydrodynamic length scale effects are crucial in the A-B transition.

A comprehensive theoretical model is established.

Abstract

A rigorous hydrodynamic theory of the A-B transition is presented. All dissipative processes are considered. At low interface velocities, those occurring on hydrodynamic length scales, not considered hitherto, are most probably the dominant ones.
