The Casimir force between metallic mirrors
In order to compare recent experimental results with theoretical predictions
we study the influence of finite conductivity of metals on the Casimir effect.
The correction to the Casimir force and energy due to imperfect reflection and
finite temperature are evaluated for plane metallic plates where the dielectric
functions of the metals are modeled by a plasma model. The results are compared
with the common approximation where conductivity and thermal corrections are
evaluated separately and simply multiplied.Comment: 10 pages, 8 figures, contribution to MG9 proceeding
The Casimir effect in the nanoworld
The Casimir effect is a force arising in the macroscopic world as a result of
radiation pressure of vacuum fluctuations. It thus plays a key role in the
emerging domain of nano-electro-mechanical systems (NEMS). This role is
reviewed in the present paper, with discussions of the influence of the
material properties of the mirrors, as well as the geometry dependence of the
Casimir effect between corrugated mirrors. In particular, the lateral component
of the Casimir force and restoring torque between metal plates with misaligned
corrugations are evaluated.Comment: 8 pages, 6 figures, contribution to CEWQO 2007 proceeding
