Lateral Casimir force beyond the proximity-force approximation.
We argue that the appropriate variable to study a nontrivial geometry dependence of the Casimir force is the lateral component of the Casimir force, which we evaluate between two corrugated metallic plates outside the validity of the proximity-force approximation. The metallic plates are described by the plasma model, with arbitrary values for the plasma wavelength, the plate separation, and th...
متن کاملThe lateral Casimir force beyond the proximity force approximation : a nontrivial interplay between geometry and quantum vacuum
The lateral Casimir force between two corrugated metallic plates makes possible a study of the nontrivial interplay of geometry and Casimir effect appearing beyond the regime of validity of the Proximity Force Approximation (PFA). Quantitative evaluations can be obtained by using scattering theory in a perturbative expansion valid when the corrugation amplitudes are smaller than the three other...
متن کاملExperimental investigation of the Casimir force beyond the proximity-force approximation.
The analysis of all Casimir force experiments using a sphere-plate geometry requires the use of the proximity-force approximation (PFA) to relate the Casimir force between a sphere and a flat plate to the Casimir energy between two parallel plates. Because it has been difficult to assess the PFA's range of applicability theoretically, we have conducted an experimental search for corrections to ...
متن کاملRoughness correction to the Casimir force : Beyond the Proximity Force Approximation
– We calculate the roughness correction to the Casimir effect as a second order perturbation of the parallel plates geometry. The metallic plates are described by the plasma model, with arbitrary values for the plasma wavelength, the plate separation and the roughness spectrum. The roughness correction is always larger than the result obtained in the Proximity Force Approximation. We derive sca...
متن کاملCasimir effect for curved geometries: proximity-force-approximation validity limits.
We compute Casimir interaction energies for the sphere-plate and cylinder-plate configuration induced by scalar-field fluctuations with Dirichlet boundary conditions. Based on a high-precision calculation using world-line numerics, we quantitatively determine the validity bounds of the proximity-force approximation (PFA) on which the comparison between all corresponding experiments and theory a...
