Quantum 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 کاملExternally mode-matched cavity quantum electrodynamics with charge-tunable quantum dots.
We present coherent reflection spectroscopy on a charge and dc Stark tunable quantum dot embedded in a high-quality and externally mode-matched microcavity. The addition of an exciton to a single-electron-charged quantum dot forms a trion that interacts with the microcavity just below the strong-coupling regime of cavity quantum electrodynamics. Such an integrated, monolithic system is a crucia...
متن کاملResonant Andreev Tunneling in Strongly Interacting Quantum Dots
We study resonant Andreev tunneling through a strongly interacting quantum dot connected to a normal and to a superconducting lead. We obtain a formula for the Andreev current and apply it to discuss the linear and non-linear transport in the nonperturbative regime, where the effects of the Kondo resonance on the two particle tunneling arise. In particular we notice an enhancement of the Kondo ...
متن کاملA tunable kondo effect in quantum dots
A tunable Kondo effect has been realized in small quantum dots. A dot can be switched from a Kondo system to a non-Kondo system as the number of electrons on the dot is changed from odd to even. The Kondo temperature can be tuned by means of a gate voltage as a single-particle energy state nears the Fermi energy. Measurements of the temperature and magnetic field dependence of a Coulomb-blockad...
