Textures in Rotating Superfluid 3He-A

Abstract

Possible textures in the rotating superfluid 3He-A are studied in the London limit. Three types of textures without singular cores, i.e., the non-singular vortex lattice, the vortex-sheet lattice and the concentric sheet structure, are explicitly constructed. The estimate of the free energy associated with each structure is made and the results indicate the first type is most stable.
