We are looking for excellent and highly motivated post-doc candidateS for the following projects:
Anyons on demand (2 years contract - ANR FullyQuantum 2018):
The Nanoelectronics Group currently has an opening for a Post-Doctoral Position on our experiment on Anyonic statistics with Fractional Levitons in the Fractional Quantum Hall Effect regime.
The candidate will lead a presently running experiment on the project on abelian and non-abelian statististics using on-demand anyon sources based on levitons in the FQHE regime. Through electronic Hong Ou Mandel interferences, the time control would permit an unprecedented measurement of the quantum statistical angle of e/3 or e/5 anyons or non-abelian anyons.

Thermal conductance of many-body quantum Hall states of graphene (2 years contract- ERC QuaHQ, 2019):
The goal of this project is to explore quantum transport of heat in new states of matter arising in ultra-clean graphene under high magnetic fields, using ultra-sensitive electronic noise measurements. This project is funded by the European Research Council (ERC-StG-2018 805080 QUAHQ).
We have an open position (starting February 2019) for a highly talented postdoctoral collaborator, with comprehensive skills in nanofabrication (in particular van der Waals heterostructures), low noise measurements, and cryogenics.

Single-charge detection for electron quantum optics (2 years post doc)
The present state of the art is to read out electron quantum optics experiments by a measurement of the average transfer probability of electrons into output ports (i.e. current) and the current noise. This project will break new ground, developing techniques for the detection of the individual single-electron wave packet.
For levitons the project will explore the use of a single-leviton induced electron-avalanche in a graphene constriction in the QHE regime, biases near breakdown, which will be detected by a measurable noise . Presently the QHE breakdown mechanisms in high-mobility h-BN graphene is unknown. The project will advance the state of the art understanding of its mechanisms and signatures, notably its ability to detect ultra-small (≤ 1 pA) DC current or short-time current pulses (yet explored in GaAs).
