vacuum.
* Idea: The QED prediction
that the vacuum is modified by the presence of boundaries, which has observable
effects; For example, two conducting uncharged
infinite parallel plates will feel an attractive force due to vacuum
fluctuations
of the field, since there are more possible zero-point fluctuations
outside the plates.
* Consequences: Tiny
as it is, the Casimir effect causes parts in nano- and microelectromechanical
systems (NEMS and MEMS) to stick together; Therefore, it confounds tabletop
experimental efforts to detect exotic new forces beyond those predicted by
Newtonian gravity and the Standard Model of particle physics.
* Calculation: One calculates
the stress tensor for the quantized electromagnetic field in the region of
interest.
* Value: For plate separation 1 micron, the force is
13
N/m2.

* At finite temperature:
2008, Different theoretical approaches lead to very different predictions
for the magnitude of the effect, and no consensus exists yet on the interpretation
of recent absolute measurements of the Casimir force.

Dynamical Casimir Effect
* Idea:
Motion-induced photon creation from the quantum vacuum inside closed,
perfectly conducting cavities with time-dependent geometries;
Related to the Unruh effect; An example is the electromagnetic radiation
of moving gravitating bodies (> gravitating
matter).
