The authors' main claim Based on the redistribution of thermal quasiparticles within the texture, we develop a model which bestows a significant effective mass on the interface, an d gives a new mechanism for friction as the boundary moves.

In this work we study the influence of orbital viscosity on the dynamics of the order parameter texture in the superfluid B-phase of $^3$He near a moving bounda ry. Based on the redistribution of thermal quasiparticles within the texture, we develop a model which bestows a significant effective mass on the interface, an d gives a new mechanism for friction as the boundary moves. We have tested the model against existing data of a moving A-B interface whose motion was controlled using magnetic field. The model allows some predictions in experimental situations which involve texture rearrangement due to the B-phase boundary motion.

The paper
Original abstract
In this work we study the influence of orbital viscosity on the dynamics of the order parameter texture in the superfluid B-phase of $^3$He near a moving bounda ry. Based on the redistribution of thermal quasiparticles within the texture, we develop a model which bestows a significant effective mass on the interface, an d gives a new mechanism for friction as the boundary moves. We have tested the model against existing data of a moving A-B interface whose motion was controlled using magnetic field. The model allows some predictions in experimental situations which involve texture rearrangement due to the B-phase boundary motion.
