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 Casimir effect for a sphere and a cylinder in front of plane and corrections to the proximity force theorem
Using a path integral approach we rederive a recently found representation of the Casimir energy for a sphere and a cylinder in front of a plane and derive the first correction to the proximity force theorem.
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 کاملGeneralized Lifshitz formula for a cylindrical plasma sheet in front of a plane beyond proximity force approximation
We calculate the first correction beyond proximity force approximation for a cylindrical graphene sheet in interaction with a flat graphene sheet or a dielectric half space.
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...
