Investigation of techniques (theory and experiment) to avoid limiting measurement back-action in precision metrology, e.g. quantum-optomechanics.
Contributions to QuantumFrontiers
- Insights to the field of quantum optomechanics at vastly different scales: from quantum optics (micro-optomechanics) to interferometric gravitational wave detection (macroscopic optomechanics, 40 kg-scale mirrors)
- Reduction of all-optical quantum radiation pressure noise (e.g. Coherent Quantum Noise Cancellation)
- Laser power stabilisation via radiation pressure
Collaborative Innovation
- Investigation of membrane-in-the-middle (MiM) / membrane-at-the-edge (MatE) optical resonators for quantum optomechanical experiments at room temperature and cryogenic temperatures (Heurs, LUH, AEI)
- Testing micro-optomechanical oscillators for cavity experiments near and below the SQL (Heurs, LUH, AEI / Kroker TUBS, PTB)
- Investigating levitated nanoparticles for gravimetry (C. Vogt, ZARM)
