Abstract:
In this paper, we study the stationary solutions of a canonical system, the matter "eld obeying an exclusion}inclusion
principle (EIP) which is minimally coupled to a gauge "eld whose dynamics are described within the frame of the
Chern}Simons picture. We show that with a suitably selected non-linear algebraic potential ;(o), we can obtain the
stationary states through the solution of a "rst-order di!erential equation aH la Bogomol'nyi. The model admits
non-topological vortex solutions whose properties are studied in detail. We derive the expressions of the main physical
quantities associated to these solutions, like the electric charge and the angular momentum and derive the vortex shape
numerically integrating proper equations. As a consequence, we obtain that the introduction of the EIP in our model
transforms in continuous quantities the electric charge and the angular momentum of the system, which are discrete in
the absence of the EIP. Finally we show that when the EIP is reduced to an exclusion principle, the value of the above
physical quantities have an upper limit.
