Figueira Física, Astronomía y Matemáticas boson Quantum dots Kondo effect Scattering phase We study the scattering phase shift of the Kondo assisted transmission through a quantum dot (QD), consideringa model that includes an additional non resonant channel transmission. To compute the phase evolutionand the transmission amplitude of the QD, for different temperatures, we describe the QD employing the singleAnderson impurity model in the limit of infinity Coulomb repulsion, within the X-boson approach. Our resultsare consistent with the development of an unusually large phase evolution at around p in the Kondo valley,observed in recent experiments, and is consistent with others theoretical treatments. 2006 artículo científico 0103-9733 https://www.redalyc.org/articulo.oa?id=46436534 en http://www.redalyc.org/revista.oa?id=464 Brazilian Journal of Physics application/pdf Sociedade Brasileira de Física Brazilian Journal of Physics (Brasil) Num.3B Vol.36 |
