Popis: | By path integration method developed by Brusov and Popov earlier we investigated the influence of textures on collective excitations in superfluid He-3. For arbitrary textures we have obtained the quadratic form of the hydrodynamic action functional, which determined the collective mode spectrum. Using this quadratic form we have calculated the whole collective mode spectrum for B-phase of helium-3 closed to boundary. The texture splits the real squashing, squashing and pair breaking-modes and leads to appearance of gaps in goldstone-mode spectrum. |
