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.

Such fields would cause effects obscuring any attraction that could be attributed to the Casimir-Polder force.
The measurements reveal the presence of an atom-plate interaction that clearly fits a Casimir-Polder force much better than it does a van der Waals force.
These experiments yielded the most precise measurements yet of energy levels to which the Casimir-Polder force makes a discernible contribution.
