VORTEX SOLUTIONS OF A MAXWELL-CHERN-SIMONS FIELD COUPLED TO 4-FERMIONTHEORY

We find the static vortex solutions of the model of a Maxwell-Chern-Si mons gauge field coupled to a (2+1)-dimensional four-fermion theory. E specially, we introduce two matter currents coupled to the gauge field minimally: the electromagnetic current and a topological current asso ciated with the electromagnetic current. Unlike other Chern-Simons sol itons the N-soliton solution of this theory has binding energy and the stability of the solutions is maintained by the charge conservation l aws.
