This paper is a continuation of a previous one [Jancovici B andŠamaj L, 2004 JSTAT P08006] dealing with classical Casimir phenomena in semi-infinite wall geometries. In that paper, using microscopic Coulomb systems, the long-ranged Casimir force due to thermal fluctuations in conducting walls was shown to be screened by the presence of an electrolyte between the walls into some residual short-r...

In net-neutral systems correlations between charge fluctuations generate strong attractive thermal Casimir forces and engineering these forces to optimize nanodevice performance is an important challenge. We show how the normal and lateral thermal Casimir forces between two plates containing Brownian charges can be modulated by decorrelating the system through the application of an electric fie...

We provide a derivation of the percolation threshold for a two-dimensional triangular lattice. We then proceed to model an ensemble of skewed square lattices with randomly punched out squares, which is topologically equivalent to triangular lattice percolation. We investigate the behavior of the magnitude of the Casimir force between the percolating plate and the solid plate. We find evidence w...

The Casimir force is calculated between plates with thin metallic coating. Thin films are described with spatially dispersive nonlocal dielectric functions. For thin films the nonlocal effects are more relevant than for half-spaces. However, it is shown that even for film thickness smaller than the mean free path for electrons, the difference between local and nonlocal calculations of the Casim...

We present a new approach to calculate the attractive long-range vortex-vortex interaction of the van der Waals type present in anisotropic and layered superconductors. The mapping of the statistical mechanics of two-dimensional charged bosons allows us to define a Casimir problem: Two half spaces of vortex matter separated by a gap of width R are mapped to two dielectric half planes of charged...
