Casimir problem of spherical dielectrics: numerical evaluation for general permittivities.
The Casimir mutual free energy F for a system of two dielectric concentric nonmagnetic spherical bodies is calculated, at arbitrary temperatures. The present paper is a continuation of an earlier investigation [Phys. Rev. E 63, 051101 (2001)], in which F was evaluated in full only for the case of ideal metals (refractive index n= infinity ). Here, analogous results are presented for dielectrics...

متن کاملCasimir Problem in Spherical Dielectrics: a Quantum Statistical Mechanical Approach
The Casimir mutual free energy F for a system of two dielectric concentric nonmagnetic spherical bodies is calculated, at arbitrary temperatures. Whereas F has recently been evaluated for the special case of metals (refractive index n = ∞), here analogous results are presented for dielectrics, and shown graphically when n = 2.0. Our calculational method relies upon quantum statistical mechanics...
متن کاملThe Casimir Problem of Spherical Dielectrics: a Solution in Terms of Quantum Statistical Mechanics
The Casimir energy for a compact dielectric sphere is considered in a novel way, using the quantum statistical method introduced by Høye-Stell and others. Dilute media are assumed. It turns out that this method is a very powerful one: we are actually able to derive an expression for the Casimir energy that contains also the negative part resulting from the attractive van der Waals forces betwee...
متن کاملCasimir problem of spherical dielectrics: quantum statistical and field theoretical approaches.
The Casimir free energy for a system of two dielectric concentric nonmagnetic spherical bodies is calculated with use of a quantum statistical mechanical method, at arbitrary temperature. By means of this rather novel method, which turns out to be quite powerful (we have shown this to be true in other situations also), we consider first an explicit evaluation of the free energy for the static c...
