Nanotechnology: Shaping the void
Astrid Lambrecht1
Abstract
A vacuum may be devoid of matter, but its shape is still important. The strength of the Casimir force caused by quantum fluctuations in the space between surfaces is critically dependent on their nanometre-scale shape.
Two reflecting plates facing each other in a vacuum attract. This startling phenomenon is known as the Casimir effect1, named after the Dutch physicist Hendrik Casimir who discovered it in 1948.
- Astrid Lambrecht is at the Laboratoire Kastler Brossel, Campus Jussieu, Case 74, 75252 Paris Cedex 05, France.
