Abstract
The spin of solitons is considered in the models coupled with the Chern-Simons gauge field. In particular, we shall examine how the large gauge fixing of the Chern-Simons gauge field is related to the expression for spin of the solitons, in both the 0(3) a-model coupled with the Chern-Simons gauge field and the Chern-Simons-Higgs model. Then, we shall show that, in order to obtain a plausible expression for the spin of the soliton, it is necessary to impose an appropriate large gauge condition on the Chern-Simons gauge field. We also comment on the relation between the spin of solitons and the extra angular momentum of static solitons.
