In 1985 a small group of UW nuclear and atomic experimentalists formed the Eöt-Wash collaboration to develop novel high-sensitivity torsion balances to test some of these theoretical scenarios and to search for subtle new phenomena associated with the breakdown of either of the 2 standard models. As our experimental sensitivity increased by orders of magnitudes, theorists proposed new mechanisms that we could test until a small “graveyard” of proposals was populated.
In 2021 this work was awarded the Breakthrough Prize in Fundamental Physics “for precision measurements that test our understanding of gravity, probe the nature of dark energy, and establish limits on couplings on dark matter.” I will review the extraordinary instruments we developed and the results we obtained from testing Einstein’s equivalence principle and the gravitational inverse-square law, and probing for Planck-scale Lorentz violation using a quantum gyroscope with no moving parts.
Speakers: Eric Adelberger, Blayne Heckel, & Jens Gundlach (2021 Breakthrough Prize in Fundamental Physics Winners), University of Washington
