Analysis of atomic-clock data to constrain variations of fundamental constants

We present a new framework to study the time variation of fundamental constants in a model-independent way. Model independence implies more free parameters than assumed in previous studies. Using data from atomic clocks based on ^87 Sr, ^171 Yb ^+ and ^133 Cs, we set bounds on parameters controlling...
