The Eöt-Wash Group:
Laboratory Tests of Gravitational and sub-Gravitational Physics
We pioneer new techniques in high-precision studies of weak-field
gravity and searches for possible new interactions weaker than gravity.
Our scientific goals:
1) Search for experimental signatures of quantum
gravity that would violate Einstein's Equivalence Principle and/or the Newtonian
inverse-square law at some length scale (which may be anywhere between the
inaccessible Planck length and infinity).
2) Probe the largely unexplored region of possible interactions weaker than gravity.
3) Make sensitive tests for new interactions that couple to electron spin.
4) Provide understanding of small short range forces that may affect the LISA gravitational wave experiment.
