PhD Scholarship in the Engineering of Quantum Sensors and Networks
Physical Sciences/Other Physical Sciences

One of the remaining puzzles in modern physics is the transition from quantum to classical physics. While many models, like decoherence, have been proposed, experimental tests remain very challenging. One of the most promising avenues for observing quantum effects at a macroscopic scale has been through optomechanics in which the radiation pressure of light is used to probe and control the dynamics of mechanical oscillators.

We seek to understand how the world works at the small scale. Quantum mechanics is the fascinating field that studies how nature works on the nano- and microscales. Several questions are still under investigation: What is the nature of the transition between the quantum mechanical laws and those of ordinary classical mechanics that large systems obey? How can one use the stronger coherences that arise in quantum systems to make possible more precise measurements or quicker computations?

PhD Scholarship in the Engineering of Hybrid Quantum Systems
Physical Sciences/Other Physical Sciences

The project is aimed at the creation and manipulation of atomic density patterns by contact-free self-assembly due to optomechanical forces. We are looking at large patches (samples size of some millimetres) of laser cooled matter (around 100 µK), which will be structured on scales of wavelengths to hundreds of micrometres. The spatial structure is not imposed externally but evolves spontaneously from an instability of the homogeneous atomic cloud in interaction with a homogeneous light field.
