Studying variation of fundamental constants with molecules
V. V. Flambaum, M. G. Kozlov
TL;DR
This review discusses how precision molecular spectroscopy can be used in astrophysics and laboratory experiments to investigate potential variations in fundamental physical constants over space and time.
Contribution
It provides a comprehensive overview of current methods and findings in using molecular spectroscopy to test the stability of fundamental constants.
Findings
Molecular spectroscopy offers sensitive probes for fundamental constant variations.
Both astrophysical data and laboratory experiments contribute to constraints.
Current results place stringent limits on possible variations.
Abstract
This review article is devoted to application of precision molecular spectroscopy to studies of the possible spatial and temporal variations of the fundamental constants. Both astrophysical observations and laboratory experiments are discussed.
