• Cold?
• For what?
• How to do?
Cold atomsCold atoms
Into a gas: cold means weak velocity distribution around a mean velocity
Precision measurements Quantum gases …
Laser cooling Evaporative cooling …
Cold molecules?Cold molecules?• High resolution spectroscopy (very long
interaction time)• Cold chemistry • Polar molecules : dipole - dipole interaction• Variation of fundamental constants with time
