Aalto University invites applications for a Postdoctoral Researcher in Quantum Optomechanics at the Department of Applied Physics. The position focuses on experimental research on exciton-polariton optomechanics using GaAs/AlAs microcavity systems to study quantum interactions between light, sound, and mechanical modes. The project aims to achieve ground-state cooling of mechanical systems and explore quantum state preparation and control. The successful candidate will lead experimental work, collaborate with international partners, supervise students, and contribute to high-impact publications in quantum optics and photonics.
