Offer Description

Post doctoral position in advanced spectroscopy measurements on polariton quantum fluids.

• Design and theoretical modelling of nonlinear polariton networks for quantum sensing — Main duty / High level of responsibility
• Experimental implementation and optical characterization of nonlinear polariton systems — Main duty / High level of responsibility
• Investigation of nonlinear dynamics, collective phenomena and quantum-state sensing protocols — Main duty / High level of responsibility
• Data acquisition, analysis and comparison with theoretical models — Main duty / Medium level of responsibility
• Numerical simulations and development of computational tools — Secondary duty / Medium level of responsibility
• Contribution to scientific publications, presentations and collaborative research activities — Secondary duty / Medium level of responsibility

The position will be hosted at the Kastler Brossel Laboratory (LKB), a leading research laboratory in quantum physics. The researcher will join the Quantum Fluids of Light and Nanophotonics team, whose research focuses on quantum fluids of light, nonlinear photonics and hybrid light–matter systems.
The recruited researcher will work on nonlinear polariton networks for quantum sensing, in close interaction with the team members, including researchers, engineers and PhD students. The position will be supervised by the project leader and will involve both independent research activities and collaborative work within the team.
