Measuring the spatio-temporal variation of fundamental physical constants using the OH sum rules
Renzhi Su, Minfeng Gu
In this paper, we introduce a method to constrain the variation of fundamental physical constants predicted by grand unified theories. This approach utilizes OH sum rules, which ex…

A stringent constraint on the fractional change of proton g-factor
Renzhi Su, Stephen J. Curran, Jeremy Darling +5
We report a constraint on the cosmological variation of the proton g-factor, . By comparing the measured redshifts between \mbox{H\,{\sc i}} 21 cm and OH 18 cm lines observed…

New constraints on the values of the fundamental constants at a look-back time of 7.3 Gyr
Renzhi Su, Stephen J. Curran, Francoise Combes +4
The study of redshifted spectral lines can provide a measure of the fundamental constants over large look-back times. Current grand unified theories predict an evolution in these c…
