Conductivity of Coulomb interacting massless Dirac particles in graphene: Regularization-dependent parameters and symmetry constraints
G. Gazzola, A. L. Cherchiglia, L. A. Cabral +2
We compute the Coulomb correction to the a. c. conductivity of interacting massless Dirac particles in graphene in the collisionless limit using the polarization tens…
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This paper has been withdrawn by the authors due to crucial error on assumption in Eq. 2.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…
Persistent currents in n-fold twisted Moebius strips
E. H. Martins Ferreira, M. C. Nemes, M. D. Sampaio +1
We investigate the influence of the topology on generic features of the persistent current in n-fold twisted Moebius strips formed of quasi one--dimensional mesoscopic rings, both…
