Physics Colloquium

"Exploring the Quantum Vacuum through the Casimir Effect"

Presented by Umar Mohideen, University of California, Riverside

Tuesday, October 18, 2005, 3:30 pm — Large Seminar Room, Bldg. 510

According to Quantum Field Theory, empty space is filled
with virtual particles, which in the case of the Electro-magnetic Force would be virtual photons. H.B.G. Casimir predicted that modifying the properties of these virtual photons, by placing boundaries such as two parallel mirrors, would lead to an observable force attracting the
two mirrors. I will discuss some of the puzzling aspects of this force, its measurement using microfabricated cantilevers and micro electromechanical machines and its role in modern technology.
