Abstract
We show that Bloch oscillations of ultracold atoms in an optical
lattice are a strong tool to measure accurately some physical
constants. We describe in this paper two experimental approaches
using a pure and an accelerated vertical standing waves to perform
respectively a determination of the local acceleration of gravity
g to ppm precision and of the fine structure constant α
with a relative uncertainty of 6,7 ppb
