Quantum physics: Casimir force changes sign
Eyal Buks & Michael L. Roukes
Abstract
This quantum attractive force induces measurable effects between ultrasmall mechanical components. New calculations indicate that systems could be engineered in which Casimir forces are repulsive.
In 1948, Hendrik Casimir calculated that the quantum fluctuations of an electromagnetic field, so-called zero-point fluctuations, give rise to an attractive force between objects1. This force is a particularly striking consequence of the quantum theory of electrodynamics (for a review, see ref.
