Temperature dependence of the Casimir effect.

The temperature dependence of the Casimir force between a real metallic plate and a metallic sphere is analyzed on the basis of optical data concerning the dispersion relation of metals such as gold and copper to be consistent with the third law of thermodynamics and not inconsistent with current experiments.

Temperature correction to Casimir-Lifshitz free energy at low temperatures: semiconductors.

The temperature correction to the Casimir-Lifshitz free energy between two parallel plates made of dielectric material possessing a constant conductivity at low temperatures, described through a Drude-type dielectrics function is calculated.

Casimir force between metallic mirrors

We study the influence of finite conductivity of metals on the Casimir effect. We put the emphasis on explicit theoretical evaluations which can help comparing experimental results with theory. The

Surface screening in the Casimir force

We calculate the corrections to the Casimir force between two metals due to the spatial dispersion of their response functions. We employ model-independent expressions for the force in terms of the

Nonretarded limit of the Lifshitz theory for a wedge

We develop the Lifshitz theory of van der Waals forces in a wedge of a dielectric material. The non-planar geometry of the problem requires determining point-wise distribution of stresses. The

Anomalous temperature dependence of the Casimir force for thin metal films.

The experimental observation of the predicted decreasing temperature dependence of theCasimir force can put an end to the long-standing discussion on the role of the electron relaxation in the Casimir effect.

Low temperature Casimir-Lifshitz free energy and entropy: The case of poor conductors

The controversy concerning the temperature correction to the Casimir force has been ongoing for almost a decade with no view to a solution and has recently been extended to include semiconducting

Microscopic Origin of Universality in Casimir Forces

The microscopic mechanisms for universality of Casimir forces between macroscopic conductors are displayed in a model of classical charged fluids. The model consists of two slabs in empty space at

Van der Waals forces

Summary Van der Waals forces are among the forces that attract atoms and molecules together. Their importance follows from two unique properties. Firstly, they are universal. All atoms and molecules

The Influence of Retardation on the London-van der Waals Forces

The influence of retardation on the energy of interaction between two neutral atoms is investigated by means of quantum electrodynamics. As a preliminary step, Part I contains a discussion of the

Evidence for the Existence of Fractional Charge on Matter

We present results of a superconducting magnetic levitation experiment which provide evidence for the existence of fractional charge on matter. Three niobium balls heat-treated on a tungsten

Casimir effect in source theory

The theory of the Casimir effect, including its temperature dependence, is rederived by source theoretic methods, which do not employ the concept of zero point energy.
