Casimir effect between dissimilar materials: a test for the proximity theorem | | Cecilia Noguea

1 Dec 2003 | | Journal: | Phys. Rev. B70, 195412 (2004) DOI: 10.1103/PhysRevB.70.195412 | | Subject: | Quantum Physics; Other; Materials Science; Chemical Physics | quant-ph cond-mat.mtrl-sci cond-mat.other physics.chem-ph | | Abstract: | We calculate exactly the Casimir force between a spherical particle and a plane, both with arbitrary dielectric properties, in the non-retarded limit. Using a Spectral Representation formalism, we show that the Casimir force of a sphere made of a material A and a plane made of a material B, differ from the case when the sphere is made of B, and the plane is made of A. The differences in energy and force show the importance of the geometry, and make evident the necessity of realistic descriptions of the sphere-plane system beyond the Proximity Theorem approximation. | | Source: | arXiv, quant-ph/0312009 | | Other source: | [GID 787556] quant-ph/0312009 | | Services: | Forum | Review | PDF | Favorites | |
