Ground state of3He-A in a sphere

    Research output: Contribution to journalArticlepeer-review


    We compare the free energies and currents of four trial states of3He-A in spherical geometries. The spherical boojum texture is found to be energetically stable for all container radii down to R ∼46ξ, where ξ is the superfluid coherence length. Textures with line defects in the bulk will become energetically favorable below this radius.
