New Experimental Limits on Non-Newtonian Forces in the Micrometer Range
New Experimental Limits on Non-Newtonian Forces in the Micrometer Range
We report measurements of the short-range forces between two macroscopic gold-coated plates using a torsion pendulum. The force is measured for separations between 0.7 $\mu$m and 7 $\mu$m, and is well described by a combination of the Casimir force, including the finite-temperature correction, and an electrostatic force due to patch …
