Towards the Calculation of Casimir Forces for Inhomogeneous Planar Media
Casimir forces arise from vacuum fluctuations. They are fully understood only for simple models, and are important in nanoand microtechnologies. We report our experience of computer algebra calculations towards the Casimir force for models involving inhomogeneous dielectrics. We describe a methodology that greatly increases confidence in any results obtained, and use this methodology to demonst...

متن کاملOn Casimir Forces for Media with Arbitrary Dielectric Properties
We derive an expression for the Casimir force between slabs with arbitrary dielectric properties characterized by their reflection coefficients. The formalism presented here is applicable to media with a local or a non-local dielectric response, an infinite or a finite width, inhomogeneous dissipative, etc. Our results reduce to the Lifshitz formula for the force between semi-infinite dielectri...
متن کاملCasimir 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...
