Long-range spin transport in asymmetric quadruple quantum dots configurations
David Fernández-Fernández, Johannes C. Bayer, Rolf J. Haug +1
We theoretically investigate long-range coherent charge transport in linear quadruple quantum dot (QQD) arrays under reduced symmetry configurations. Employing a master equation ap…
Interplay between Hund's rule and Kondo effect in a quantum dot
Olfa Dani, Johannes C. Bayer, Timo Wagner +2
The interaction between localized spins on a quantum dot and free electrons in the reservoirs forms a many-particle entangled system giving rise to the Kondo effect. Here, we inves…
Real-Time Detection and Control of Correlated Charge Tunneling in a Quantum Dot
Johannes C. Bayer, Fredrik Brange, Adrian Schmidt +4
We experimentally demonstrate the real-time detection and control of correlated charge tunneling in a dynamically driven quantum dot. Specifically, we measure the joint distributio…
Revealing Hidden States in Quantum Dot Array Dynamics: Quantum Polyspectra Versus Waiting Time Analysis
Markus Sifft, Johannes C. Bayer, Daniel Hägele +1
Quantum dots (QDs) are pivotal for the development of quantum technologies, with applications ranging from single-photon sources for secure communication to quantum computing infra…
