We investigate transport in a three-terminal graphene quantum dot. All nine elements of the conductance matrix have been independently measured. In the Coulomb blockade regime accurate measurements of...
Abstract: We experimentally investigate the dynamic nonlinear response of a single quantum dot (QD) strongly coupled to a photonic crystal cavity-waveguide structure. The temporal response is measured...
Abstract: We study dynamics of the interaction between two weak light beams mediated by a strongly coupled quantum dot-photonic crystal cavity system. First, we perform all optical switching of a weak...
Abstract: We discuss the fine-tuning of the optical properties of self-assembled quantum dots by the strain perturbation introduced by laser-induced surface defects. We show experimentally that the qu...
Abstract: We have employed Bloch-wave engineering to realize submicron diameter ultra-high quality factor GaAs/AlAs micropillars (MPs). The design features a tapered cavity in which the fundamental Bl...
We have measured a graphene double quantum dot device with multiple electrostatic gates that are used to enhance control to investigate it. At low temperatures the transport measurements reveal hone...
We investigate out of equilibrium transport through an orbital Kondo system realized in a single quantum dot, described by the multiorbital impurity Anderson model. Shot noise and current are calculat...
Large conditional phase shifts from coupled atom-cavity systems are a key requirement for building a spin photon interface. This in turn would allow the realisation of hybrid quantum information schem...
We report on the coherent reflection spectroscopy of a high-quality factor micropillar, in the strong coupling regime with a single InGaAs annealed quantum dot. The absolute reflectivity measurement i...
We calculate the mesoscopic admittance G(!) of a double quantum dot, which can be measured directly using microwave techniques. This quantity shows a rich behavior. In particular, it is directly sens...
We present transport measurements of a tunable silicon metal-oxide-semiconductor double quantum dot device with lateral geometry. Experimentally extracted gate-to-dot capacitances show that the device...
In mesoscopic systems with spin-orbit coupling, spin-injection into quantum dots at zero magnetic eld is expected under a wide range of conditions. However, up to now, a viable approach for experimen...
We study the influence of the phonon environment on the electron dynamics in a doped quantum dot molecule.A non-perturbative quantumkinetic theory based on correlation expansion is used in order to de...
Motivated by the recent discovery of a canyon of conductance suppression in a two-level equal spin quantum dot system [Nilsson et al. Phys. Rev. Lett. 104, 186804 (2010)] the transport through this sy...
Semiconductor quantum dots have been a subject of intensive investigation over last two decades. One reason is the proposal [1] to use spin state of electron in a quantum dot as a quantum bit of inf...
