Frequency shift of cesium clock transition due to blackbody radiation
E. J. Angstmann, V. A. Dzuba, V. V. Flambaum
We have performed ab initio calculations of the frequency shift induced by a static electric field on the cesium clock hyperfine transition. The calculations are used to find the f…
Frequency shift of hyperfine transitions due to blackbody radiation
E. J. Angstmann, V. A. Dzuba, V. V. Flambaum
We have performed calculations of the size of the frequency shift induced by a static electric field on the clock transition frequencies of the hyperfine splitting in Yb+, Rb, Cs,…
A New Option for a Search for Alpha Variation: Narrow Transitions with Enhanced Sensitivity
S. G. Karshenboim, A. Yu. Nevsky, E. J. Angstmann +2
We consider several transitions between narrow lines that have an enhanced sensitivity to a possible variation of the fine structure constant, alpha. This enhancement may allow a s…
Parity nonconservation in Atomic Zeeman Transitions
E. J. Angstmann, T. H. Dinh, V. V. Flambaum
We discuss the possibility of measuring nuclear anapole moments in atomic Zeeman transitions and perform the necessary calculations. Advantages of using Zeeman transitions include…
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…
Atomic Clocks and the Search for Variation of the Fine Structure Constant
E. J. Angstmann, V. A. Dzuba, V. V. Flambaum
Evidence that the fine structure constant, alpha, was different in an early epoch has recently been found in quasar (QSO) absorption spectra. An accurate laboratory measurement of…
