  A model unifying superconductivity and antiferromagnetism using an underlying
approximate SO(5) symmetry has injected energy into the field of
high-temperature superconductivity. This model might lead to a variety of
interesting solitons. In this paper, the idea that superconducting vortices may
have antiferromagnetic cores is presented, along with the results of some
preliminary numerical work. An outlook for future work, including speculations
about other possible exotic solitons, is presented.
