Tunable g-Factors of Hybridized Orbitals in a Quantum Dot Molecule
Michelle Lienhart, Krzysztof Gawarecki, Pavel Daskalov +10
The ability to control the -factors of orbital spin states in optically active quantum dot molecules (QDMs) is a prerequisite for the high-fidelity generation of multi-photonic…
Purcell enhanced and blinking free single photons from InAs/GaAs quantum dots in deterministically placed circular Bragg gratings
Peter Gschwandtner, Quirin Buchinger, Krishna Chand Maurya +11
The paper demonstrates a bright, charge‑tunable, blinking‑free single‑photon source based on InAs quantum dots embedded in a p‑i‑n GaAs membrane and coupled to a modified circular…
Spectral shadows of a single GaAs quantum dot
Kai Hühn, Lena Klar, Fei Ding +4
Semiconductor quantum dots are a promising platform for generating single and entangled photons.Still, their use is limited even in the most advanced structures by changes in the c…
Exciton-resonant detection of high-frequency surface acoustic waves from subwavelength metal gratings
Olga Ken, Dmytro Horiachyi, Ilya Akimov +8
We report on all-optical generation and detection of high-frequency (up to about 30 GHz) surface acoustic waves (SAWs) in GaAs/AlGaAs heterostructures with short-period Au gratings…
Exchange interaction in gate-defined quantum dots beyond the Hubbard model
Alexander Willmes, Patrick Bethke, M. Mohamed El Kordy Shehata +10
A quantitative description of the exchange interaction in quantum dots is relevant for modeling gate operations of spin qubits. By measuring the amplitude and frequency of exchange…
Eigenstate control of plasmon wavepackets with electron-channel blockade
Shintaro Takada, Giorgos Georgiou, Junliang Wang +8
Coherent manipulation of plasmon wavepackets in solid-state systems is crucial for advancing nanoscale electronic devices, offering a unique platform for quantum information proces…
