A model for stationary electronic transport through a one‐dimensional chain of two leads attached to a perturbed central region (quantum dot) is presented. In the investigated regime a theory for a similar model of phonon transport recently proposed by Čápek predicts a striking phenomenon of permanent current between the leads. This result, based on a rigorous but asymptotic Davies theory, is in contradiction to the zero current yielded by direct transport calculations which can be carried out in the presented model. The permanent current is found to be within the error of the asymptotic expansion for finite couplings, and cancelling terms of the same order are identified.
