Structure of surface layer in superfluid 3He-B
Volovik G.E.
Four types of surface states are described at a boundary between3 He-B and a vessel near the transition to3 He-A. In this region, these states are interfaces [ (3 He-B) — (3Не-Л) or (3He-5) — (planarphase) interfaces] which are pinned by the boundary of the vessel.
