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…

Big bang nucleosynthesis as a probe of fundamental "constants"

Thomas Dent, Steffen Stern

Big Bang nucleosynthesis (BBN) is the earliest sensitive probe of the values of many fundamental particle physics parameters. We have found the leading linear dependences of primor…

Primordial nucleosynthesis as a probe of fundamental physics parameters

Thomas Dent, Steffen Stern, Christof Wetterich

We analyze the effect of variation of fundamental couplings and mass scales on primordial nucleosynthesis in a systematic way. The first step establishes the response of primordial…
