Journal ArticleDOI
New determination of the fine structure constant and test of the quantum electrodynamics.
TL;DR: In this article, a new measurement of the ratio between the Planck constant and the mass of an atom was reported, with a relative uncertainty of $6.6\times 10^{-10}.
Journal ArticleDOI
Determination of the fine-structure constant with an accuracy of 81 parts per trillion
TL;DR: The value of the fine-structure constant α differs by more than 5 standard deviations from the best available result from caesium recoil measurements, which modifies the constraints on possible candidate dark-matter particles proposed to explain the anomalous decays of excited states of 8Be nuclei and paves the way for testing the discrepancy observed in the magnetic moment anomaly of the muon in the electron sector.
Journal ArticleDOI
Combination of BLOCH oscillations with a Ramsey-Bordé interferometer: new determination of the fine structure constant.

TL;DR: The deduced value of h/mRb leads to a new determination of the fine structure constant alpha(-1) =137.03599945 (62) with a relative uncertainty of 4.6 x 10(-9) and provides the most stringent test of QED.

TL;DR: The GBAR project as mentioned in this paper proposes to measure the free fall acceleration of neutral antihydrogen atoms in the terrestrial gravitational field by photoionizing them with Be+ ions to a few 10 μ K.
