Spin polarisation signatures of Fractionally Charged Skyrmions in Fractional Quantum Hall states
Odysseas Williams, Stefan Faelt, Christian Reichl +1
We investigate spin polarisation and low-energy excitations in fractional quantum Hall (FQH) states using cavity-polariton spectroscopy of high-mobility GaAs quantum wells. By meas…
Frequency-resolved decoherence spectroscopy of a semiconductor charge qubit coupled to a high-impedance resonator
Ekaterina Al-Tavil, Wonjin Jang, David J. van Woerkom +10
Superconducting resonators coupled to semiconductor quantum dots provide a powerful platform to investigate light-matter interaction and decoherence mechanisms in solid-state quant…
Compact self-matched gyrators using edge magnetoplasmons
Aldo Tarascio, Yiqi Zhao, Rafael S. Eggli +5
Edge magnetoplasmons provide a natural platform for chiral electrodynamics, where broken time-reversal symmetry enforces unidirectional propagation. When probed at microwave freque…
Impact of Layer Structure and Strain on Morphology and Electronic Properties of InAs Quantum Wells on InP (001)
Zijin Lei, Yuze Wu, Christian Reichl +2
High-quality InAs quantum wells grown on InP are a promising platform for topological quantum information processing due to their large g-factor, strong Rashba spin-orbit interacti…
An InAsSb surface quantum well with in-situ deposited Nb as a platform for semiconductor-superconductor hybrid devices
Sjoerd Telkamp, Zijin Lei, Tommaso Antonelli +7
We present a novel semiconductor-superconductor hybrid material based on a molecular beam epitaxially grown InAsSb surface quantum well with an in-situ deposited Nb top layer. Rela…
Entropy of a double quantum dot
David Kealhofer, Christoph Adam, Max J. Ruckriegel +7
We use charge sensing to detect entropy changes in a double quantum dot defined by electrostatic gating of a GaAs/AlGaAs heterostructure. This system can be tuned to be two separat…
