摘要

We study a Skyrme-type model with a quadratic potential for a field with S2 vacua. The model contains molecules of half Skyrmions, each of them is a global (anti-)monopole with baryon number 1=2. We numerically construct solutions with baryon numbers one through six, and find stable solutions which look like beads on rings. We also construct a molecule with fractional Skyrmions having the baryon numbers 1=3+2=3, by adding a linear potential term.
