We produce ultracold molecules by direct laser cooling. We are using these to:
- Study collisions between ultracold atoms and molecules and cool molecules to quantum degeneracy
- Explore many-body quantum physics using ordered arrays of interacting molecules
- Develop a molecule chip where trapped molecules can interact strongly with microwave photons
- Develop a clock based on the fundamental vibrational transition of a molecule and use it to test the stability of fundamental constants
- Measure the electron's electric dipole moment.

Buffer Gas CoolingMolecules are produced inside a cell containing a buffer gas of cold helium. They are cooled by the helium and flow out of the cell forming an intense, low temperature, low-velocity beam. |
