| Recent experiments on ultracold atoms in optical lattices (made of laser light) have used Bloch oscillations to measure gravity and also the fine structure constant to high precision. I will discuss theoretical calculations upon a variant of this idea, namely atoms that move in the optical lattice formed inside an optical cavity pumped by a laser. A cavity allows for a very strong atom-light interaction and the signature of the atomic Bloch oscillations can become imprinted onto the light transmitted by the cavity thus allowing for very high precision measurements. |
