N2 - We describe a method for sensing short range forces using matter-wave interference in dielectric nanospheres. When compared with atom interferometers, the larger mass of the nanosphere results in reduced wave-packet expansion, enabling investigations of forces nearer to surfaces in a free-fall interferometer. By laser cooling a nanosphere to the ground state of an optical potential and releasing it by turning off the optical trap, acceleration sensing at the 10-8m/s2 level is possible. The approach can yield improved sensitivity to Yukawa-type deviations from Newtonian gravity at the 5μm length scale by a factor of 104 over current limits.
