Cavity Cooling of Many Atoms

We demonstrate cooling of an atomic ensemble from 200 µK to 10 µK in 100ms using an optical cavity and light that is far detuned from the atomic transitions. The cavity modifies the atomic emission spectrum which allows us to extract thermal kinetic energy from the atomic system. I'll describe the experiment and our cooling method, place it in the context of other common atomic cooling methods, and provide outlook for applying this technique to cool more atoms with more complicated energy level diagrams.  (Preprint : arXiv:1701.01226)
