Abstract:
We use Bloch oscillations to coherently transfer many photon momenta to atoms. Then we can measure accurately the recoil velocity ħk/m and deduce the fine structure constant α. The velocity variation due to Bloch oscillations is measured using atom interferometry. This method yields a value of the fine structure constant α-1 = 137.035 999 45 (62) with a relative uncertainty of about 4.5 × 10-9.
