| contents | We show that three-dimensional spherical-shell condensates respond to rotation by forming two aligned triangular Abrikosov-like vortex lattices on each hemispherical surface. The centrifugal force due to rotation causes an elliptical deformation of the spherical shell condensate shape and for faster rotation rates, drives the formation of a central multi-charged vortex-antivortex pair at the poles surrounded by a ring of singly charged vortices in the bulk density. The vortex distributions observed in each hemisphere take a similar form to those found in rotating harmonic plus quartic traps. |
