Cavity-mediated coherent coupling between distant quantum dots
Giorgio Nicolí, Michael Sven Ferguson, Clemens Rössler +7
Scalable architectures for quantum information technologies require to selectively couple long-distance qubits while suppressing environmental noise and cross-talk. In semiconducto…
Non-linear and dot-dependent Zeeman splitting in GaAs/AlGaAs quantum dot arrays
V. P. Michal, T. Fujita, T. A. Baart +5
We study the Zeeman splitting in lateral quantum dots that are defined in GaAs-AlGaAs het- erostructures by means of split gates. We demonstrate a non-linear dependence of the spli…
Scanning gate experiments: from strongly to weakly invasive probes
R. Steinacher, C. Pöltl, T. Krähenmann +8
An open resonator fabricated in a two-dimensional electron gas is used to explore the transition from strongly invasive scanning gate microscopy to the perturbative regime of weak…
A capacitance spectroscopy-based platform for realizing gate-defined electronic lattices
T. Hensgens, U. Mukhopadhyay, P. Barthelemy +6
Electrostatic confinement in semiconductors provides a flexible platform for the emulation of interacting electrons in a two-dimensional lattice, including in the presence of gauge…
Edge channel confinement in a bilayer graphene -- quantum dot
Hiske Overweg, Peter Rickhaus, Marius Eich +6
We combine electrostatic and magnetic confinement to define a quantum dot in bilayer graphene. The employed geometry couples -doped reservoirs to a -doped dot. At magnetic fi…
Landau polaritons in highly non-parabolic 2D gases in the ultra-strong coupling regime
Janine Keller, Giacomo Scalari, Felice Appugliese +11
We probe ultra-strong light matter coupling between metallic terahertz metasurfaces and Landau-level transitions in high mobility 2D electron and hole gases. We utilize heavy-hole…
Electrostatically induced quantum point contact in bilayer graphene
Hiske Overweg, Hannah Eggimann, Xi Chen +10
We report the fabrication of electrostatically defined nanostructures in encapsulated bilayer graphene, with leakage resistances below depletion gates as high as G.…
Long-range spin-coherence in a strongly-coupled all electronic dot-cavity system
Michael Sven Ferguson, David Oehri, Clemens Rössler +4
We present a theoretical analysis of spin-coherent electronic transport across a mesoscopic dot-cavity system. Such spin-coherent transport has been recently demonstrated in an exp…
Deterministic entanglement between a propagating photon and a singlet--triplet qubit in an optically active quantum dot molecule
Yves L. Delley, Martin Kroner, Stefan Fält +2
Two-electron charged self-assembled quantum dot molecules exhibit a decoherence-avoiding singlet-triplet qubit subspace and an efficient spin-photon interface. We demonstrate quant…
Lateral p-n Junction in an Inverted InAs/GaSb Double Quantum Well
Matija Karalic, Christopher Mittag, Thomas Tschirky +3
We present transport measurements on a lateral p-n junction in an inverted InAs/GaSb double quantum well at zero and nonzero perpendicular magnetic fields. At a zero magnetic field…
Quantum simulation of a Fermi-Hubbard model using a semiconductor quantum dot array
T. Hensgens, T. Fujita, L. Janssen +6
Interacting fermions on a lattice can develop strong quantum correlations, which lie at the heart of the classical intractability of many exotic phases of matter. Seminal efforts a…
Distinct evolutions of Weyl fermion quasiparticles and Fermi arcs with bulk band topology in Weyl semimetals
N. Xu, G. Autes, C. E. Matt +14
The Weyl semimetal phase is a recently discovered topological quantum state of matter characterized by the presence of topologically protected degeneracies near the Fermi level. Th…
Coherent shuttle of electron-spin states
T. Fujita, T. A. Baart, C. Reichl +2
We demonstrate a coherent spin shuttle through a GaAs/AlGaAs quadruple-quantum-dot array. Starting with two electrons in a spin-singlet state in the first dot, we shuttle one elect…
Gate-Defined One-Dimensional Channel and Broken Symmetry States in MoS van der Waals Heterostructures
Riccardo Pisoni, Yongjin Lee, Hiske Overweg +7
We have realized encapsulated trilayer MoS devices with gated graphene contacts. In the bulk, we observe an electron mobility as high as 7000~cm/(V s) at a density of 3 $…
Polaron-Polaritons in the Integer and Fractional Quantum Hall Regimes
Sylvain Ravets, Patrick Knüppel, Stefan Faelt +3
Elementary quasi-particles in a two dimensional electron system can be described as exciton-polarons since electron-exciton interactions ensures dressing of excitons by Fermi-sea e…
