Atomic Quantum Optics
Prof. Dr. Morgan Mitchell
- Activities:
We study quantum physics as it manifests in atomic and optical systems, especially quantum processes arising from light-atom interactions. One major area of research is atomic quantum sensors, for which we have developed hot-vapor, laser-cooled, and ultra-cold atomic systems. With these we have demonstrated entanglement-enhanced sensing of magnetic fields, and more generally are working to understand how entanglement and other quantum effects can improve quantum sensor technology. Another area of interest is fundamental quantum physics at the light-atom interface. For this we work with individual trapped atoms and ultracold atoms. Finally, we study quantum randomness and its relationship to technology and foundations of physics.
