Strong enhancement of the persistent current by an embedded quantum dot
E. H. Martins Ferreira, M. C. Nemes, H. A. Weidenmueller
This paper has been withdrawn by the authors due to crucial error on assumption in Eq. 2. We cannot assume v_R and v_L to be equal or even have the same sign.

Persistent current on a disordered mesoscopic ring with an embedded quantum dot
E. H. Martins Ferreira, M. C. Nemes, H. A. Weidenmueller
We calculate the ensemble averaged persistent current on disordered mesoscopic rings with an embedded quantum dot. We model the quantum dot as a single resonance and use Random Mat…
