Casimir effect

[′kaz·ə‚mir i‚fekt]
(quantum mechanics)
An attractive force between two parallel, conducting plates in empty space that arises from zero-point quantum fluctuations of the vacuum electromagnetic field and is proportional to 1/ d 4, where d is the plate separation.

"We know these Casimir forces exist, so, what we're trying to do is figure out the overall impact they have very small particles."
For CEM, several algorithms have been developed to handle large scale, multi- physics problems that can be adapted to solve the Casimir force problem.
In present study, the governing equation of motion of nano/microbeams under the combined effect of electrostatic excitation due to ramp-input voltage and the Casimir force has been derived.
In the situation of a Casimir effect setup, considered here, these divergences do not depend on the width of the gap and the Casimir force is always finite.
Harvard physicist Federico Capasso, a member of the group who measured the effect, said that that the Casimir force needn't be an enemy.
Eight physicists introduce physics related to the Casimir force and vacuum energies.
The presence of unevenness on the surface of the plates causes lateral Casimir force. Such lateral force has resulted in some suggestions for designing a new type of nanomachines."As the contact between the pieces of nanomachines causes erosion in the pieces at small scales, we looked for a method to reduce such erosion," Mojtaba Nasiri Zarandi, one of the researchers of this project, told the Iran Nanotechnology Initiative Council."In the suggested system, there is no physical contact between the pieces.

86) cites the attraction between a gold plate and a ball as proof of vacuum energy and the Casimir force, but isn't it possible that science has jumped the gun?
This paper presents an extended analysis of the ZPE frequency spectrum and its effect on the Casimir force, thereby leading to proposed experimental investigations on the features of the same spectrum.
