Josephson effect through a quantum dot array
F. S. Bergeret, A. Levy Yeyati, A. Martin-Rodero
We analyze the ground state properties of an array of quantum dots connected in series between superconducting electrodes. This system is represented by a finite Hubbard chain coup…
Nonhomogeneous magnetization and superconductivity in superconductor-ferromagnet structures
F. S. Bergeret, A. F. Volkov, K. B. Efetov
We study two different superconductor-ferromagnet (S/F) structures. We consider first a Josephson junction which consists of two S/F bilayers separated by an insulating layer. We s…
Density of states and supercurrent in diffusive SNS junctions: role of nonideal interfaces and spin-flip scattering
J. C. Hammer, J. C. Cuevas, F. S. Bergeret +1
We present a theoretical study of the density of states and supercurrent in diffusive superconductor-normal metal-superconductor (SNS) junctions. In particular, we study the influe…
