Temperature dependence of the Casimir effect.
The temperature dependence of the Casimir force between a real metallic plate and a metallic sphere is analyzed on the basis of optical data concerning the dispersion relation of metals such as gold and copper. Realistic permittivities imply, together with basic thermodynamic considerations, that the transverse electric zero mode does not contribute. This results in observable differences from ...
متن کاملWhat is the temperature dependence of the Casimir effect?
Recently there has been a comment [1] that has strongly criticized our work [2] on the temperature dependence of the Casimir force between a spherical lens and a plate, both coated with real metals (Au for example). This follows a long paper by some of the same authors [3], which also criticizes our work as being in conflict with fundamental thermodynamical requirements, particularly the third ...

متن کاملComment on "temperature dependence of the Casimir effect".
Recently, Brevik [Phys. Rev. E, 71, 056101 (2005)] adduced arguments against the traditional approach to the thermal Casimir force between real metals and in favor of one of the alternative approaches. The latter assume zero contribution from the transverse electric mode at zero frequency in qualitative disagreement with unity as given by the thermal quantum field theory for ideal metals. Those...
متن کاملCasimir energies: temperature dependence, dispersion, and anomalies.
Assuming the conventional Casimir setting with two thick parallel perfectly conducting plates of large extent with a homogeneous and isotropic medium between them, we discuss the physical meaning of the electromagnetic field energy W disp when the intervening medium is weakly dispersive but nondissipative. The presence of dispersion means that the energy density contains terms of the form d[ome...
