Gate tunable edge magnetoplasmon resonators
E. Frigerio, G. Rebora, M. Ruelle +11
Quantum Hall systems are platforms of choice when it comes to study topological properties of condensed matter systems and anyonic exchange statistics. In this work we have develop…
Electronic bandstructure of superconducting KTaO3 (111) interfaces
Srijani Mallik, Börge Göbel, Hugo Witt +17
Two-dimensional electron gases(2DEGs)based on KTaO3 are emerging as a promising platform for spin-orbitronics due to their high Rashba spin-orbit coupling (SOC) and gate-voltage tu…
Electroluminescence and Energy Transfer Mediated by Hyperbolic Polaritons
L. Abou-Hamdan, A. Schmitt, R. Bretel +26
Under high electrical current, some materials can emit electromagnetic radiation beyond incandescence. This phenomenon, referred to as electroluminescence, leads to the efficient e…
Emission of photon multiplets by a dc-biased superconducting circuit
G. C. Ménard, A. Peugeot, C. Padurariu +12
We observe the emission of bunches of photons by a circuit made of a microwave resonator in series with a voltage-biased tunable Josephson junction. The bunches are…
Generating two continuous entangled microwave beams using a dc-biased Josephson junction
A. Peugeot, G. Ménard, S. Dambach +14
We show experimentally that a dc-biased Josephson junction in series with two microwave resonators emits entangled beams of microwaves leaking out of the resonators. In the absence…
Closing of the Induced Gap in a Hybrid Superconductor-Semiconductor Nanowire
D. Puglia, E. A. Martinez, G. C. Ménard +8
Hybrid superconductor-semiconductor nanowires are predicted to undergo a field-induced phase transition from a trivial to a topological superconductor, marked by the closure and re…
End-to-end correlated subgap states in hybrid nanowires
G. L. R. Anselmetti, E. A. Martinez, G. C. Ménard +9
End-to-end correlated bound states are investigated in superconductor-semiconductor hybrid nanowires at zero magnetic field. Peaks in subgap conductance are independently identifie…
Conductance-matrix symmetries of a three-terminal hybrid device
G. C. Ménard, G. L. R. Anselmetti, E. A. Martinez +10
We present conductance-matrix measurements of a three-terminal superconductor-semiconductor hybrid device consisting of two normal leads and one superconducting lead. Using a symme…
Suppressing quasiparticle poisoning with a voltage-controlled filter
Gerbold C. Ménard, Filip K. Malinowski, Denise Puglia +5
We study single-electron charging events in an Al/InAs nanowire hybrid system with deliberately introduced gapless regions. The occupancy of a Coulomb island is detected using a ne…
Long range coherent magnetic bound states in superconductors
Gerbold C. Ménard, Sébastien Guissart, Christophe Brun +9
The quantum coherent coupling of completely different degrees of freedom is a challenging path towards creating new functionalities for quantum electronics. Usually the antagonisti…
