"A Measurement of the Casimir Force between Two Spheres"

by Joe Garrett

Friday, March 3, 2017 -- 12:00 p.m.
Large Conference Room, 1207 Energy Research Facility

Advisor:  Prof. Jeremy Munday

Quantum fluctuations cause an attractive force between uncharged surfaces, which is called the Casimir force at separations > 20 nm. Most measurements of the Casimir force are performed in the sphere-plate geometry because it is invariant to motion in the x-y plane and rotations of the sphere. However, other geometries are better suited to show evidence of non-additivity and deviations from the proximity force approximation, and may even lead to repulsion. I will discuss our measurements of the Casimir force between two spheres and the bounds it allows us to put on deviations from the proximity force approximation.
