Single-parameter quantized charge pumping in high magnetic fields
B. Kaestner, Ch. Leicht, V. Kashcheyevs +3
We study single-parameter quantized charge pumping via a semiconductor quantum dot in high magnetic fields. The quantum dot is defined between two top gates in an AlGaAs/GaAs heter…
A quantum criticality perspective on the charging of narrow quantum-dot levels
V. Kashcheyevs, C. Karrasch, T. Hecht +3
Understanding the charging of exceptionally narrow levels in quantum dots in the presence of interactions remains a challenge within mesoscopic physics. We address this fundamental…
Manipulation of Dark States and Control of Coherent Processes with Spectrally Broad Light
Marcis Auzinsh, Nikolai Bezuglov, Kaspars Miculis
The formation of dark states under interaction of degenerate atomic states with incoherent broadband radiation (white light) is discussed. A simple coupling scheme in a three level…
Low-frequency excitation of double quantum dots
Vyacheslavs Kashcheyevs
We address theoretically adiabatic regime of charge transport for a model of two tunnel-coupled quantum dots connected in series. The energy levels of the two dots are harmonically…
History and results of the Riga dynamo experiments
Agris Gailitis, Gunter Gerbeth, Thomas Gundrum +3
On 11 November 1999, a self-exciting magnetic eigenfield was detected for the first time in the Riga liquid sodium dynamo experiment. We report on the long history leading to this…
Ionization of Rydberg atoms by blackbody radiation
I. I. Beterov, D. B. Tretyakov, I. I. Ryabtsev +3
We have studied an ionization of alkali-metal Rydberg atoms by blackbody radiation (BBR). The results of the theoretical calculations of ionization rates of Li, Na, K, Rb and Cs Ry…
