We discuss repulsive Casimir forces between dielectric materials with nontrivial magnetic susceptibility. It is shown that considerations based on the naive pairwise summation of van der Waals and Casimir-Polder forces may not only give an incorrect estimate of the magnitude of the total Casimir force but even the wrong sign of the force when materials with high dielectric and magnetic responses are involved. Indeed repulsive Casimir forces may be found in a large range of parameters, and we…

Is repulsive Casimir force physical

The Casimir force for charge-neutral, perfect conductors of non-planar geometric configurations have been investigated. The configurations are: (1) the plate-hemisphere, (2) the hemisphere-hemisphere

Repulsive Casimir force in Bose–Einstein Condensate

We study the Casimir effect for a three dimensional system of ideal free massive Bose gas in a slab geometry with Zaremba and anti-periodic boundary conditions. It is found that for these type of

Opposites attract: a theorem about the Casimir Force.

A proof that the Casimir force between two bodies related by reflection is always attractive, independent of the exact form of the bodies or dielectric properties.

Repulsive Casimir forces and the role of surface modes

The Casimir repulsion between a metal and a dielectric suspended in a liquid has been thoroughly studied in recent experiments. In the present paper we consider surface modes in three layered systems

Repulsive and Restoring Casimir Forces Based on Magneto-Optical Effect

The Casimir force direction tuned by the external magnetic field due to the magneto-optical Voigt effect is investigated. The magneto-optical effect gives rise to the modified frequency-dependent

Casimir force between designed materials: What is possible and what not

We establish strict upper limits for the Casimir interaction between multilayered structures of arbitrary dielectric or diamagnetic materials. We discuss the appearance of different power laws due to

The Casimir force becomes increasingly important as mechanical devices are down-scaled into the micron range. We suggest here that artificial periodic materials with feature sizes in the nanometer

Repulsive and attractive Casimir forces in a glide-symmetric geometry

We describe a three-dimensional geometry that exhibits a repulsive Casimir force using ordinary metallic materials, as computed via an exact numerical method (no uncontrolled approximations). The


In this paper, we study the zero and finite temperature Casimir force acting on a perfectly conducting rectangular piston inside a closed rectangular cavity with infinitely permeable walls. Explicit

Casimir Force in Non-Planar Geometric Configurations

The Casimir force for charge-neutral, perfect conductors of non-planar geometric configurations have been investigated. The configurations are: (1) the plate-hemisphere, (2) the hemisphere-hemisphere



The Casimir Effect and Its Applications

The Casimir effect is analyzed. This effect consists of a polarization of the vacuum of quantized fields which arises as a result of a change in the spectrum of vacuum oscillations when the
