Search for a Spin-Dependent Short-Range Force

The existence of possible short-range forces related to unpolarized and polarized particles has attracted the attention of physicists for decades. These forces provide a possible new source for the parity (P ) and time reversal (T ) symmetry violation. Moody and Wilczek [1] proposed that a macroscopic force with an interaction range from cm to μm can couple to scalar and pseudoscalar vertices t...

Short-range force detection using optically cooled levitated microspheres.

We propose an experiment using optically trapped and cooled dielectric micro-spheres for the detection of short-range forces. The center-of-mass motion of a microsphere trapped in vacuum can experience extremely low dissipation and quality factors of 10(12), leading to yoctonewton force sensitivity. Trapping the sphere in an optical field enables positioning at less than 1 μm from a surface, a ...

Modeling and analysis of a three-component piezoelectric force sensor

This paper presents a mathematical model for the vibration analysis of a three-component piezoelectric force sensor. The cubic theory of weakly nonlinear electroelasticity is applied to the model for describing the electromechanical coupling effect in the piezoelectric sensing elements which operate in thickness-shear and thickness-stretch vibration modes. Hamilton's principle is used to derive...
