  A type-II superconductor survives in an external magnetic field by admitting
an Abrikosov lattice of quantized vortices. This is an imprint of the
Aharonov-Bohm effect created by the Abelian U(1) gauge field. The simplest
non-Abelian analogue of such a gauge field, which belongs to the SU(2) symmetry
group, can be found in topological insulators. Here we discover a
superconducting ground state with a lattice of SU(2) vortices in a simple
two-dimensional model that presents an SU(2) "magnetic" field (invariant under
time-reversal) to attractively interacting fermions. The model directly
captures the correlated topological insulator quantum well, and approximates
one channel for instabilities on the Kondo topological insulator surface. Due
to its simplicity, the model might become amenable to cold atom simulations in
the foreseeable future. The vitality of low-energy vortex states born out of
SU(2) "magnetic" fields is promising for the creation of incompressible vortex
liquids with non-Abelian fractional excitations.
