Selective tuning of spin-orbital Kondo contributions in parallel-coupled quantum dots
Heidi Potts, Martin Leijnse, Adam Burke +4
We use co-tunneling spectroscopy to investigate spin-, orbital-, and spin-orbital Kondo transport in a strongly confined system of InAs double quantum dots (QDs) parallel-coupled t…
Imaging the Thermalization of Hot Carriers After Thermionic Emission Over a Polytype Barrier
Fabian Könemann, I-Ju Chen, Sebastian Lehmann +2
The thermalization of non-equilibrium charge carriers is at the heart of thermoelectric energy conversion. In nanoscale systems, the equilibration length can be on the order of the…
Ultrafast Optical Generation of Coherent Bright and Dark Surface Phonon Polaritons in Nanowires
Pierre-Adrien Mante, Daniel Finkelstein Shapiro, Sebastian Lehmann +3
The coherence of polaritons plays a fundamental role in numerous recent experimental observations, from strong coupling to Bose-Einstein condensation, but accessing the coherence o…
Electrical control of spins and giant g-factors in ring-like coupled quantum dots
Heidi Potts, I-Ju Chen, Athanasios Tsintzis +5
Emerging theoretical concepts for quantum technologies have driven a continuous search for structures where a quantum state, such as spin, can be manipulated efficiently. Central t…
Individually addressable double quantum dots formed with nanowire polytypes and identified by epitaxial markers
David Barker, Sebastian Lehmann, Luna Namazi +4
Double quantum dots (DQDs) hold great promise as building blocks for quantum technology as they allow for two electronic states to coherently couple. Defining QDs with materials ra…
Spatial Control of Multiphoton Electron Excitations in InAs Nanowires by Varying Crystal Phase and Light Polarization
Erik Mårsell, Emil Boström, Anne Harth +14
We demonstrate the control of multiphoton electron excitations in InAs nanowires (NWs) by altering the crystal structure and the light polarization. Using few-cycle, near-infrared…
