Further Evidence for Cosmological Evolution of the Fine Structure Constant
John K. Webb,Michael T. Murphy,Victor V. Flambaum,V. A. Dzuba,John D. Barrow,Christopher W. Churchill,Jason X. Prochaska,Arthur M. Wolfe +7 more
TL;DR: The results of a search for time variability of the fine structure constant alpha using absorption systems in the spectra of distant quasars find no systematic effects which can explain the results.
Journal ArticleDOI
Possible evidence for a variable fine structure constant from QSO absorption lines: Motivations, analysis and results
Michael T. Murphy,John K. Webb,Victor V. Flambaum,V. A. Dzuba,Christopher W. Churchill,Jason X. Prochaska,John D. Barrow,Arthur M. Wolfe +7 more
TL;DR: In this article, the authors present a detailed description of their methods and results based on an analysis of 49 quasar absorption systems (towards 28 QSOs) covering the redshift range 0:5
Journal ArticleDOI
Space-Time Variation of Physical Constants and Relativistic Corrections in Atoms
TL;DR: In this paper, it is demonstrated that high sensitivity to the variation of the fine structure constant can be obtained from a comparison of the spectra of heavy and light atoms, and some possibilities for observing enhanced effects in variations of the fundamental constants in laboratory measurements are also discussed.
Journal ArticleDOI
Single-ion nuclear clock for metrology at the 19th decimal place.
TL;DR: A virtual clock transition composed of stretched states within the 5F(5/2) electronic ground level of both nuclear ground and isomeric manifolds is proposed and is shown to offer unprecedented systematic shift suppression, allowing for clock performance with a total fractional inaccuracy approaching 1×10(-19).
Journal ArticleDOI
Calculations of the relativistic effects in many-electron atoms and space-time variation of fundamental constants
TL;DR: In this paper, a range of atoms and ions, most of which are commonly detected in quasar spectra, are used to constrain the variation of the fine-structure constant.
