Casimir energy of dielectric systems
This paper is devoted to study of Casimir effect [ 1] in dielectrics at zero temperature in the framework of quantum field theory. The presentation of the subject is based on the results and proofs derived by the author. The paper is organized as follows. In section 2 a new formula for the Casimir energy of a dispersive dilute dielectric ball [ 2] is discussed. In section 3 a path-integral meth...
متن کامل0 Casimir energy and dilute dielectric ball
General formalism of quantum field theory and addition theorem for Bessel functions are applied to derive formula for CasimirPolder energy of interaction between a polarizable particle and a dilute dielectric ball. The equivalence of dipole-dipole interaction and Casimir energy for dilute homogeneous dielectrics is shown. A novel method is used to derive Casimir energy of a dilute dielectric ba...
متن کاملCasimir Energy for a Dielectric Cylinder
In this paper we calculate the Casimir energy for a dielectric-diamagnetic cylinder with the speed of light differing on the inside and outside. Although the result is in general divergent, special cases are meaningful. The well-known results for a uniform speed of light are reproduced. The self-stress on a purely dielectric cylinder is shown to vanish through second order in the deviation of t...
متن کامل0 Casimir - Polder energy and dilute dielectric ball : nondispersive case
We apply general formalism of quantum field theory and addition theorem for Bessel functions to derive formula for the Casimir-Polder energy of interaction between a polarizable particle and a dilute dielectric ball and Casimir energy of a dilute dielectric ball. The correspondence between the Casimir-Polder formula and Casimir energy of a dilute dielectric ball is shown. Different approaches t...
متن کاملCasimir Effect for a Dielectric Wedge
The Casimir effect is considered for a wedge with opening angle α, with perfectly conducting walls, when the interior region is filled with an isotropic and nondispersive medium with permittivity ǫ and permeability μ. The electromagnetic energy-momentum tensor in the bulk is calculated, together with the surface stress on the walls. A discussion is given on the possibilities for measuring the i...
