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…
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…
Spin noise spectroscopy in GaAs
M. Oestreich, M. Roemer, R. J. Haug +1
We observe the noise spectrum of electron spins in bulk GaAs by Faraday rotation noise spectroscopy. The experimental technique enables the undisturbed measurement of the electron…
Kondo effect in a few-electron quantum ring
U. F. Keyser, C. Fuhner, S. Borck +4
A small quantum ring with less than 10 electrons was studied by transport spectroscopy. For strong coupling to the leads a Kondo effect is observed and used to characterize the spi…
