Highly charged ions for atomic clocks and search for variation of the fine structure constant
V. A. Dzuba, V. V. Flambaum
We review a number of highly charged ions which have optical transitions suitable for building extremely accurate atomic clocks. This includes ions from Hf to U, wh…
Nuclear-spin dependent parity violation in diatomic molecular ions
A. Borschevsky, M. Iliaš, V. A. Dzuba +3
Nuclear-spin-dependent (NSD) parity violating (PV) effects can be strongly enhanced in diatomic molecules containing heavy atoms. Future measurements are anticipated to provide nuc…
Isotope shift calculations in Ti II
J. C. Berengut, V. V. Flambaum, M. G. Kozlov
We present an accurate ab initio method of calculating transition energies and isotope shifts in the 3d-transition metals. It extends previous work that combines the configuration-…
Enhanced effect of temporal variation of the fine structure constant in diatomic molecules
V. V. Flambaum
We show that the relative effect of variation of the fine structure constant in microwave transitions between very close and narrow rotational-hyperfine levels may be enhanced 2-3…
Laboratory spectroscopy and the search for space-time variation of the fine structure constant using QSO spectra
J. C. Berengut, V. A. Dzuba, V. V. Flambaum +4
Theories unifying gravity with other interactions suggest spatial and temporal variation of fundamental ``constants'' in the Universe. A change in the fine structure constant, alph…
Does the fine structure constant vary? A detailed investigation into systematic effects
M. T. Murphy, J. K. Webb, V. V. Flambaum +1
We have previously presented 5.7-sigma evidence for a smaller alpha at redshifts 0.2 < z_abs < 3.7 from a sample of 128 Keck/HIRES quasar absorption systems: da/a = (-0.57 +/- 0.10…
