The 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 کامل1 4 Ju n 20 05 The Casimir force at high temperature
– The standard expression of the high-temperature Casimir force between perfect conductors is obtained by imposing macroscopic boundary conditions on the electromagnetic field at metallic interfaces. This force is twice larger than that computed in microscopic classical models allowing for charge fluctuations inside the conductors. We present a direct computation of the force between two quantu...
متن کاملCasimir force at both nonzero temperature and finite conductivity.
We find the combined effect of nonzero temperature and finite conductivity onto the Casimir force between real metals. Configurations of two parallel plates and a sphere (lens) above a plate are considered. Perturbation theory in two parameters (the relative temperature and the relative penetration depth of zero-point oscillations into the metal) is developed. Perturbative results are compared ...
متن کاملMeasurement of the temperature dependence of the Casimir-Polder force.
We report on the first measurement of a temperature dependence of the Casimir-Polder force. This measurement was obtained by positioning a nearly pure 87Rb Bose-Einstein condensate a few microns from a dielectric substrate and exciting its dipole oscillation. Changes in the collective oscillation frequency of the magnetically trapped atoms result from spatial variations in the surface-atom forc...
متن کاملTemperature Dependence of the Casimir Force Between Real Metals
Recently there have been two papers by a combined experimental and theoretical collaboration [1, 2] that have strongly criticized our work on the temperature dependence of the Casimir force between a spherical lens and a plate, both coated with real metals (Au for example) [3]. They criticize our work as being in conflict with fundamental thermodynamical requirements, particularly the third law...
