Opposites attract: a theorem about the Casimir Force.
نویسندگان
چکیده
We consider the Casimir interaction between (nonmagnetic) dielectric bodies or conductors. Our main result is a proof that the Casimir force between two bodies related by reflection is always attractive, independent of the exact form of the bodies or dielectric properties. Apart from being a fundamental property of fields, the theorem and its corollaries also rule out a class of suggestions to obtain repulsive forces, such as the two hemisphere repulsion suggestion and its relatives.

Spectral representation of the Casimir Force Between a Sphere and a Substrate
We develop a spectral representation formalism to calculate the Casimir force, in the non-retarded limit, or van der Waals force between a spherical particle and a substrate, both with arbitrary local dielectric properties. The spectral formalism allows to study the system as a function of its geometrical properties separately from its dielectric properties. The calculated force is attractive, ...
متن کاملTHE CRiTiCaL CaSimiR EFFECT UNIVERSAL FLUCTUATION - INDUCED FORCES aT WORk
It is well known that nothing comes from nothing. In physics, however, this is not always the case. Surprisingly indeed, two electrically neutral conducting metallic plates placed in vacuum about half a micrometer apart attract each other, even at zero temperature, due to a force which was theoretically predicted in 1948 by the Dutch physicist Hendrik Casimir [1]. This force originates from the...
متن کاملDynamic and Static Pull-in instability of electrostatically actuated nano/micro membranes under the effects of Casimir force and squeezed film damping
In the current study, the effects of Casimir force and squeeze film damping on pull-in instability and dynamic behavior of electrostatically actuated nano and micro electromechanical systems are investigated separately. Linear elastic membrane theory is used to model the static and dynamic behavior of the system for strip, annular and disk geometries. Squeeze film damping is modeled using nonli...
متن کاملNUMERICAL ANALYSIS OF THE CASIMIR EFFECT DUE TO A SCALAR FIELD
In this paper, we study the Casimir effect of a scalar field with Dirichlet boundary condition in some certain topologies. By numerical analysis we show that Casimir energy is a shape-dependent quantity. We also obtain the phase transition in different topologies in which the Casimir force changes from attractive to repulsive or vice versa. eararqr
متن کاملThe Casimir force on a piston in Randall-Sundrum models
The Casimir effect of a piston for massless scalar fields which satisfy Dirichlet boundary conditions in the context of five-dimensional Randall-Sundrum models is studied. In these scenarios we derive and calculate the expression for the Casimir force on the piston. We also discuss the Casimir force in the limit that one outer plate is moved to the remote place to show that the nature of the re...
