Abstract
We study some (1+2)-dimensional field-theory models with charge- fermions. The topological solitons in the models are charge- bosons and neutral fermions. There are two kinds of the magnetic vortex in the condensed state of the charge- bosons. One carries flux and another carries flux plus a neutral fermion. Charge- boson condensation and fluxoids may coexist in our models. The vortex is a boson, while the vortex is a fermion in two dimensions. Our models provide a nontrivial check of a general assertion, i.e., the flux always has a finite energy in the superconducting state of a charge- fermion system.
