Magnetic blackbody shift of hyperfine transitions for atomic clocks
J. C. Berengut, V. V. Flambaum, J. King-Lacroix
We derive an expression for the magnetic blackbody shift of hyperfine transitions such as the cesium primary reference transition which defines the second. The shift is found to be…
Effect of quark-mass variation on big bang nucleosynthesis
J. C. Berengut, V. F. Dmitriev, V. V. Flambaum
We calculate the effect of variation in the light-current quark mass, , on standard big bang nucleosynthesis. A change in at during the era of nucleosynthesis affects nu…
A proposed experimental method to determine -sensitivity of splitting between ground and 7.6 eV isomeric states in Th-229
J. C. Berengut, V. A. Dzuba, V. V. Flambaum +1
The 7.6 eV electromagnetic transition between the nearly degenerate ground state and first excited state in the Th-229 nucleus may be very sensitive to potential changes in the fin…
