Abstract: We calculate the condensate and the vacuum current density induced byexternal static magnetic fields in 2+1-dimensions. At the perturbative level,we consider an exponentially decaying magnetic field along one cartesiancoordinate. Non-perturbatively, we obtain the fermion propagator in thepresence of a uniform magnetic field by solving the Schwinger-Dyson equation inthe rainbow-ladder approximation. In the large flux limit, we observe that boththese quantities, either perturbative inhomogeneous and non-perturbativehomogeneous, are proportional to the external field, in agreement with earlyexpectations.
