Quantum Optics Group

The group research area is centered on the quantum properties of light that is produced by many different optical systems. It consists of experimental and theoretical studies concerning quantum fluctuations of light, generation of entangled states, interaction between quantum light and matter, nanophotonics, and quantum metrology.

PostDoc Position: Analogue Gravity in polariton superfluids

PostDoc Position: Analogue Gravity in polariton superfluids

Analogue gravity enables the study of fields on curved spacetimes in the laboratory [1]: it is possible to create conditions in which waves in media propagate as though they were in the vicinity of a black hole [2] or on an expanding universe [3], for example. In the...
