    • Analysis of the phase lapse problem in closed interferometers 

      Tolea, M.; Moldoveanu, V.; Dinu, I. V.; Tanatar, Bilal (Elsevier B.V., 2012)
      We investigate the connection between the asymmetry of the Fano resonances in a mesoscopic interferometer with an embedded quantum dot and the π lapses in the phase of the bare dot transmittance. Consecutive Fano resonances ...
    • Electronic transmittance phase extracted from mesoscopic interferometers 

      Tolea, M.; Moldoveanu V.; Dinu I.V.; Tanatar, Bilal (2012)
      The usual experimental set-up for measuring the wave function phase shift of electrons tunneling through a quantum dot (QD) embedded in a ring (i.e., the transmittance phase) is the so-called 'open' interferometer as first ...
    • Mesoscopic Fano effect in a spin splitter with a side-coupled quantum dot 

      Moldoveanu, V.; Tolea, M.; Tanatar, Bilal (Elsevier B.V., 2012)
      We investigate the interplay between the spin interference and the Fano effect in a three-lead mesoscopic ring with a side-coupled quantum dot (QD). A uniform Rashba spin-orbit coupling and a perpendicular magnetic field ...
    • Mesoscopic fano effect in Aharonov-Bohm rings with an embedded double dot 

      Tanatar, Bilal; Moldoveanu, V.; Tolea, M.; Aldea, A. (American Institute of Physics, 2006)
      We investigate theoretically in a tight-binding model the transport properties of the Aharonov-Bohm interferometer (ABI) with one dot embedded in each of its arms. For weak interdot coupling the model Hamiltonian describes ...
    • Mesoscopic Fano effect in an Aharonov-Bohm interferometer Coulomb-coupled to a nearby quantum dot 

      Tolea, M.; Moldoveanu, V.; Tanatar, Bilal (Wiley, 2007)
      Motivated by the pionieering experiments of Buks et al. [Nature 391, 871 (1998)] we investigate the visibility of the Fano effect in a single-dot Aharonov-Bohm interferometer which is Coulomb-coupled to a nearby quantum ...
