- 論文の詳細を見る
The stability of textures is investigated for superfluid ^3He-A contained between two coaxial cylinders without the external fields and flow. The free energies of textures depend on the ratio, R, of the outer cylinder radius (R_2) to the inner one (R_1). For R<R_c (R_c≃10^2 for the dipole locked case and ≃10^4 for the dipole free case), the radial texture is found to be most stable in contrast to the Mermin-Ho texture in the case of a cylinder. For R>R_c, we find the stable textures with non zero circulation quantum number, which induce the superfluid current about the cylinder axis in the same way as the Mermin-Ho texture does.
