Search for non-Newtonian interactions at micrometer scale with a levitated test mass
Charles P. Blakemore, Alexander Fieguth, Akio Kawasaki +5
We report on a search for non-Newtonian forces that couple to mass, with a characteristic scale of m, using an optically levitated microsphere as a precision force sens…
Absolute pressure and gas species identification with an optically levitated rotor
Charles P. Blakemore, Denzal Martin, Alexander Fieguth +4
The authors describe a novel variety of spinning-rotor vacuum gauge in which the rotor is a m-diameter silica microsphere, optically levitated. A rotating elec…
Precision Mass and Density Measurement of Individual Optically Levitated Microspheres
Charles P. Blakemore, Alexander D. Rider, Sandip Roy +4
We report an mass measurement of approximately-m-diameter, optically levitated microspheres with an electrostatic co-levitation technique. The mas…
Electrically Driven, Optically Levitated Microscopic Rotors
Alexander D. Rider, Charles P. Blakemore, Akio Kawasaki +3
We report on the electrically driven rotation of m-radius, optically levitated dielectric microspheres. Electric fields are used to apply torques to a microsphere's permanen…
Three-dimensional force-field microscopy with optically levitated microspheres
Charles P. Blakemore, Alexander D. Rider, Sandip Roy +3
We report on the use of 4.7-m-diameter, optically levitated, charged microspheres to image the three-dimensional force field produced by charge distributions on an Au-coated, mi…
