Boundary layer (on the order of the correlation length) in 3He-B
Fal'ko V. I.
A symmetry classification is offered for the states of the boundary layer in 3He-B. The first-order phase transition observed in a gyroscopic experiment by Pekola and Simola [J. Low Temp. Phys. 58, 555(1985)] can be explained as a reorientation of a boundary layer. A model is proposed for the dynamics of the transition from the В phase to the A phase.
