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…
New supersymmetric quartet of nuclei in the A=190 mass region
J. Barea, R. Bijker, A. Frank +10
We present evidence for a new supersymmetric quartet in the A=190 region of the nuclear mass table. New experimental information on transfer and neutron capture reactions to the od…
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…
Non-malleable encryption of quantum information
Andris Ambainis, Jan Bouda, Andreas Winter
We introduce the notion of "non-malleability" of a quantum state encryption scheme (in dimension d): in addition to the requirement that an adversary cannot learn information about…
