optomechanics

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?

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.
