The Indiana short-range gravity experiment uses a resonant technique to investigate forces in the sub-millimeter range with femtonewton sensitivity. It has most recently been used in a search for Lorentz violation and is currently being modified to be sensitive to electron spin-dependent forces. The ARIADNE experiment, under construction at Indiana, uses an NMR technique to probe nuclear spin-dependent forces on a sample of polarized helium-3 and will have sensitivity relevant to the hypothetical axion.
