Skyrmions and Nuclei
Nicholas Manton University of Cambridge
Skyrme proposed a field theory model of protons, neutrons and larger nuclei in which the building blocks are topological solitons in 3D -- Skyrmions -- each carrying one unit of baryon number. I will
review recent progress on this proposal, and show examples of classical multi-Skyrmions with baryon numbers up to about 100. Quantization leads to
proton and neutron states with spin half and, for example, a reasonable spectrum for the Carbon-12 nucleus. This includes the ground state band,
and the Hoyle state together with its excitations.
