Competing bounds on the present-day time variation of fundamental constants
Thomas Dent, Steffen Stern, Christof Wetterich
We compare the sensitivity of a recent bound on time variation of the fine structure constant from optical clocks with bounds on time varying fundamental constants from atomic cloc…
Dynamical dark energy and variation of fundamental "constants"
Steffen Stern
In this thesis we study the influence of a possible variation of fundamental "constants" on the process of Big Bang Nucleosynthesis (BBN). Our findings are combined with further st…
Time variation of fundamental couplings and dynamical dark energy
Thomas Dent, Steffen Stern, Christof Wetterich
Scalar field dynamics may give rise to a nonzero cosmological variation of fundamental constants. Within different scenarios based on the unification of gauge couplings, the variou…
Unifying cosmological and recent time variations of fundamental couplings
Thomas Dent, Steffen Stern, Christof Wetterich
A number of positive and null results on the time variation of fundamental constants have been reported. It is difficult to judge whether or not these claims are mutually consisten…
