Abstract

The Lifshitz formalism for determining the attractive force between material bodies with generalized electromagnetic susceptibility is applied numerically to gold, copper, and aluminum. The deviation from the perfect conductivity Casimir force approximately agrees with a first-order plasma model calculation at large separation, but at separations corresponding to the plasma frequency, deviations of over 50{percent} from the first-order model are found, while deviations from corrections up to second order are about 10{percent}. These results are discussed in the context of recent measurements of the Casimir force. {copyright} {ital 1999} {ital The American Physical Society}

Surface-impedance approach solves problems with the thermal Casimir force between real metals

Journal Article Geyer, B ; Klimchitskaya, G L ; Mostepanenko, V M - Physical Review. A

The surface-impedance approach to the description of the thermal Casimir effect in the case of real metals is elaborated starting from the free energy of oscillators. The Lifshitz formula expressed in terms of the dielectric permittivity depending only on frequency is shown to be inapplicable in the frequency region where a real current may arise leading to Joule heating of the metal. The standard concept of a fluctuating electromagnetic field on such frequencies meets difficulties when used as a model for the zero-point oscillations or thermal photons in the thermal equilibrium inside metals. Instead, the surface impedance permits not tomore »« less

Quantum and thermal Casimir interaction between a sphere and a plate: Comparison of Drude and plasma models

Journal Article Zandi, Roya ; Mohideen, Umar ; Emig, Thorsten ; ... - Physical Review. B, Condensed Matter and Materials Physics

We calculate the Casimir interaction between a sphere and a plate, both described by the plasma model, the Drude model, or generalizations of the two models. We compare the results at both zero and finite temperatures. At asymptotically large separations we obtain analytical results for the interaction that reveal a nonuniversal, i.e., material-dependent interaction for the plasma model. The latter result contains the asymptotic interaction for Drude metals and perfect reflectors as different but universal limiting cases. This observation is related to the screening of a static magnetic field by a London superconductor. For small separations we find corrections tomore »« less

Scattering theory approach to electrodynamic Casimir forces

Journal Article Rahi, Sahand Jamal ; Kardar, Mehran ; Kavli Institute for Theoretical Physics, University of California, Santa Barbara, Santa Barbara, California 93106 ; ... - Physical Review. D, Particles Fields

We give a comprehensive presentation of methods for calculating the Casimir force to arbitrary accuracy, for any number of objects, arbitrary shapes, susceptibility functions, and separations. The technique is applicable to objects immersed in media other than vacuum, nonzero temperatures, and spatial arrangements in which one object is enclosed in another. Our method combines each object's classical electromagnetic scattering amplitude with universal translation matrices, which convert between the bases used to calculate scattering for each object, but are otherwise independent of the details of the individual objects. The method is illustrated by rederiving the Lifshitz formula for infinite half-spaces, bymore »« less

Thermal Casimir interaction between two magnetodielectric plates

Journal Article Geyer, B ; Klimchitskaya, G L ; North-West Technical University, Millionnaya Street 5, St. Petersburg 191065 ; ... - Physical Review. B, Condensed Matter and Materials Physics

We investigate the thermal Casimir interaction between two magnetodielectric plates made of real materials. On the basis of the Lifshitz theory, it is shown that for diamagnets and for paramagnets in the broad sense (with exception of ferromagnets) the magnetic properties do not influence the magnitude of the Casimir force. For ferromagnets, taking into account the realistic dependence of magnetic permeability on frequency, we conclude that the impact of magnetic properties on the Casimir interaction arises entirely from the contribution of the zero-frequency term in the Lifshitz formula. The computations of the Casimir free energy and pressure are performed formore »« less

A microscopic approach to Casimir and Casimir–Polder forces between metallic bodies

Journal Article Barcellona, Pablo ; Passante, Roberto - Annals of Physics

We consider the Casimir–Polder interaction energy between a metallic nanoparticle and a metallic plate, as well as the Casimir interaction energy between two macroscopic metal plates, in terms of the many-body dispersion interactions between their constituents. Expressions for two- and three-body dispersion interactions between the microscopic parts of a real metal are first obtained, both in the retarded and non-retarded limits. These expressions are then used to evaluate the overall two- and three-body contributions to the macroscopic Casimir–Polder and Casimir force, and to compare them with each other, for the two following geometries: metal nanoparticle/half-space and half-space/half-space, where all themore »« less
