Limits on a Dynamically Varying Fine Structure Constant
E. J. Angstmann, V. V. Flambaum, S. G. Karshenboim
We show that using the modified form of the Dirac Hamiltonian as suggested by Bekenstein, does not affect the analysis in [1-4] of QSO data pertaining to a measurement of alpha var…

Relativistic effects in two valence electron atoms and ions and the search for variation of the fine structure constant
E. J. Angstmann, V. A. Dzuba, V. V. Flambaum
We perform accurate calculations of the dependence of transition frequencies in two valence electron atoms and ions on a variation of the fine structure constant, alpha. The relati…
