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…
Beam-Offset Thermoreflectance with Bayesian Optimization to Measure the Anisotropic Thermal Properties of Semiconductor Superlattices
A. Chatterjee, N. Spitzer, T. Kruck +5
The directional nature of heat conduction in semiconductor superlattices--marked by significant differences between in-plane and cross-plane pathways--poses substantial challenges…
Near transform-limited single photons from rapid-thermal annealed quantum dots
Hendrik Mannel, Fabio Rimek, Marcel Zoellner +5
Single-photon emitters are essential components for quantum communication systems, enabling applications such as secure quantum key distribution and the long-term vision of a quant…
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…
