High sensitivity, levitated microsphere apparatus for short-distance force measurements
Akio Kawasaki, Alexander Fieguth, Nadav Priel +3
A high sensitivity force sensor based on dielectric microspheres in vacuum, optically trapped by a single, upward-propagating laser beam, is described. Off-axis parabolic mirrors a…
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…
Measurement of the Newtonian Constant of Gravitation by Precision Displacement Sensors
Akio Kawasaki
The Newtonian constant of gravitation historically has the largest relative uncertainty over all other fundamental constants with some discrepancies in values between different…
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…
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…
Search for Kilogram-scale Dark Matter with Precision Displacement Sensors
Akio Kawasaki
The search for dark matter has been performed mainly for weakly interacting massive particles and massive compact halo objects, and the intermediate mass region has not been invest…
