50-Conductance fluctuations in Coulomb-blockaded dots: from the sequential theory to a quantum coherent description, L. E. F. Foa Torres , C. H. Lewenkopf and H. M. Pastawski Physica E: Low-dimensional Systems and Nanostructures, 22 (1-3), 526-529 ( 2004), Abstract: We present a quantum coherent approach to describe electronic transport through quantum dots in the Coulomb-blockade regime. Our approach contains the standard sequential theory in the limit of very weak coupling. We show that our approach explains some puzzles on the statistics of conductance peak heights raised by recent experiments. @ 2003 Elsevier B.V. All rights reserved.
