Probing new physics at the precision frontier

In this talk we discuss different methods to probe new light physics at the precision frontier. Isotope shifts are measurements of atomic spectral lines (electronic transitions) in different isotopes. We discuss the sensitivity of these measurements to probe new long range forces by using King and generalized King analyses in the light of the new experimental results. 

Finally, we discuss the possibility to prove axion-like-particles by superconducting radio-frequency cavities.
