Fluids of light constitute novel and flexible systems of effectively interacting photons that exhibit many fascinating properties of quantum gases: superfluidity, condensation or topological effects to cite a few. To achieve a fluid of light, a very simple approach consists in propagating a quasi-monochromatic fluid of light in a nonlinear Kerr medium. In the paraxial limit, the evolution of the beam is then described by an effective nonlinear Schrödinger equation. The post-doctoral researcher will theoretically study these systems beyond the paraxial approximation, in configurations where a spin-orbit interaction shows up and modifies the physics of the fluid of light. The position is funded by the ANR project "CONFOCaL", and it might involve collaborations with the "quantum optics" team at LKB and the "cold atoms" group at Institut de Physique de Nice. The problems tackled will concern (not exclusively) the effect of spin-orbit interactions on light superfluidity, on the dynamics of (pre-)thermalization or on the Casimir forces induced by the fluid of light.
- Development of a theoretical description of spin-orbit interactions in fluids of light
- Study of superfluidity, of the non-equilibrium dynamics and (pre-)thermalization of light in the presence of spin-orbit coupling
- Supervision of PhD students
The candidate is required to have an excellent knowledge of the quantum physics of cold atoms and the associated theoretical approaches. An expertise of non-equilibrium systems would be a strong asset. The recruited postdoc will be a highly dynamic, creative and motivated, and able to work independently and to regularly communicate with the team. The candidate must be fluent in English.
The post-doctoral researcher will be funded by the ANR project "CONFOCaL", aimed to explore the physics of complex fluids of light. He/she will work in the "Complex quantum systems" team of LKB, in a rich scientific environment at the heart of Paris (Sorbonne université site). Visits to the theoretical and experimental collaborators will be also organized.
