Non-Equilibrium Josephson and Andreev Current through Interacting Quantum Dots
We present a theory of transport through interacting quantum dots coupled to normal and superconducting leads in the limit of weak tunnel coupling. A Josephson current between two superconducting leads, carried by first-order tunnel processes, can be established by non-equilibrium proximity effect. Both Andreev and Josephson current is suppressed for bias voltages below a threshold set by the C...
متن کاملNon-equilibrium quantum dots: transport
The electronic transport through three-dimensionally confined semiconductor ’quantum dots’ is investigated and analyzed. The spectrum corresponds to resonant tunneling from laterally confined emitter contact subbands through the discrete three-dimensionally confined quan tum dot states. Momentum non-conservation is observed in these structures.
متن کاملQuantum Dots and Andreev Reflections in Graphene Quantum Dots and Andreev Reflections in Graphene
Preface By the end of my Master's thesis in University of Groningen in 2006, I was convinced that I wanted to do a PhD working on cold atoms. However, Marius Costache, who was at that moment a PhD student in Groningen, urged me to apply also to the quantum transport group (QT) in Delft. So I did. During my interview in Delft, QT people impressed me for being exceptionally smart and at the same ...
متن کاملAndreev quantum dots for spin manipulation.
We investigate the feasibility of manipulating individual spin in a superconducting junction where Bogoliubov quasiparticles can be trapped in discrete Andreev levels. We call this system an Andreev quantum dot (AQD) to be contrasted with a common semiconductor quantum dot. We show that the AQD can be brought into a spin-1/2 state. The coupling between the spin and superconducting current facil...
متن کاملPhonon affected transport through molecular quantum dots.
To describe the interaction of molecular vibrations with electrons at a quantum dot contacted to metallic leads, we extend an analytical approach that we previously developed for the many-polaron problem. Our scheme is based on an incomplete variational Lang-Firsov transformation, combined with a perturbative calculation of the electron-phonon self-energy in the framework of generalized Matsuba...
