Our group explores quantum fluids of light to study emergent many-body phenomena, such as superfluidity or turbulence. Quantum fluids of light can be experimentally realized within microscopic optical cavities, where the photons are trapped in intricate lattice or box potentials. With this experimental platform, we investigate novel topological physics, the interplay of quantum effects and dissipation, and quantum communication. Unravelling such open questions is at the forefront of today’s research in quantum physics and may lead to new applications for future quantum technologies.
