Heat equilibration of integer and fractional quantum Hall edge modes in graphene
Gaëlle Le Breton, Raphaëlle Delagrange, Yuanzhuo Hong +7
Hole-conjugate states of the fractional quantum Hall effect host counter-propagating edge channels which are thought to exchange charge and energy. These exchanges have been the su…
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…
Unveiling excitonic properties of magnons in a quantum Hall ferromagnet
A. Assouline, M. Jo, P. Brasseur +8
Magnons enable transferring a magnetic moment or spin over macroscopic distance. In quantum Hall ferromagnet, it has been predicted in the early 90s that spin and charges are entan…
Electronic wave-packets in integer quantum Hall edge channels: relaxation and dissipative effects
G. Rebora, D. Ferraro, R. H. Rodriguez +3
We theoretically investigate the evolution of the peak height of an energy resolved electronic wave-packets ballistically propagating along integer quantum Hall edge channels at fi…
Quantum Hall valley splitters and tunable Mach-Zehnder interferometer in graphene
M. Jo, P. Brasseur, A. Assouline +10
Graphene is a very promising test-bed for the field of electron quantum optics. However, a fully tunable and coherent electronic beam splitter is still missing. We report the demon…
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…
