The Casimir force between rough metallic plates
– The Casimir force between two metallic plates is affected by their roughness state. This effect is usually calculated through the so-called 'proximity force approximation' which is only valid for small enough wavevectors in the spectrum of the roughness profile. We introduce here a more general description with a wavevector-dependent roughness sensitivity of the Casimir effect. Since the prox...
متن کاملThe Casimir Force between Real Mirrors at Non Zero Temperature
The Casimir force between dissipative metallic mirrors at non zero temperature has recently given rise to contradictory claims which have raised doubts about the theoretical expression of the force. In order to contribute to the resolution of this difficulty, we come back to the derivation of the force from basic principles of the quantum theory of lossy optical cavities. We obtain an expressio...
متن کاملThe Casimir force for passive mirrors
We show that the Casimir force between mirrors with arbitrary frequency dependent reflectivities obeys bounds due to causality and passivity properties. The force is always smaller than the Casimir force between two perfectly reflecting mirrors. For narrow-band mirrors in particular, the force is found to decrease with the mirrors bandwidth.

متن کاملMeasurement of the Casimir force between parallel metallic surfaces.
We report on the measurement of the Casimir force between conducting surfaces in a parallel configuration. The force is exerted between a silicon cantilever coated with chromium and a similar rigid surface and is detected by looking at the shifts induced in the cantilever frequency when the latter is approached. The scaling of the force with the distance between the surfaces was tested in the 0...
متن کاملCasimir Energy and Entropy between Dissipative Mirrors
We discuss the Casimir effect between two identical, parallel slabs, emphasizing the role of dissipation and temperature. Starting from quite general assumptions, we analyze the behavior of the Casimir entropy in the limit T → 0 and link it to the behavior of the slab’s reflection coefficients at low frequencies. We also derive a formula in terms of a sum over modes, valid for dissipative slabs...
