Fundamental constants are a cornerstone of our physical laws. Any constant varying in
space and/or time would reflect the existence of an almost massless field that couples to …

We have previously presented evidence for a varying fine-structure constant, α, in two
independent samples of Keck/HIRES quasi-stellar object (QSO) absorption spectra. Here we …

The effect of variations of the fundamental nuclear parameters on big-bang nucleosynthesis
are modeled and discussed in detail taking into account the interrelations between the …

We calculate the dependence of the nuclear magnetic moments on the quark masses,
including the spin-spin interaction effects, and obtain limits on the variation of the fine …

Ultracold molecules offer brand new opportunities to probe the variation of fundamental
constants with unprecedented sensitivity. This paper summarizes theoretical background …

We perform calculations of the dependence of nuclear magnetic moments on quark masses
and obtain limits on the variation of the fine structure constant α and (mq/Λ QCD) from recent …

We present evidence for variations in the fine-structure constant from Keck/HIRES spectra of
143 quasar absorption systems over the redshift range 0.2< z abs< 4.2. This includes 15 …

We use big bang nucleosynthesis calculations and light element abundance data to
constrain the relative variation of the deuteron binding energy since the Universe was a few …

We examine how the binding of light (A⩽ 8) nuclei depends on possible variations of
hadronic masses, including meson, nucleon, and nucleon-resonance masses. Small …

A bstract We present an improved calculation of the light element abundances in the
framework of Big Bang nucleosynthesis as a function of the Higgs vacuum expectation value …
