Van der Waals-Casimir-Polder interaction of an atom with a composite surface
Van der Waals-Casimir-Polder interaction atom composite surface Atomic Physics
2012/5/29
We study the dispersion interaction of the van der Waals and Casimir-Polder (vdW-CP) type between a neutral atom and the surface of a metal by allowing for nonlocal electrodynamics, i.e. electron diff...
Temperature (in)dependence of the Casimir-Polder potential of a particle near a metallic sphere
Casimir-Polder potential particle metallic sphere Temperature independence
2011/8/16
Abstract: It has recently been shown that the Casimir-Polder potential of a particle in an energy eigenstate near a conducting body can be virtually temperature independent, provided the separation be...

The trace of a function of a Schrodinger operator minus the same for the Laplacian can be expressed in terms of the determinant of its scattering matrix. The naive formula for this determinant is dive...
We study the zero point energy of massless scalar and vector fields subject to spheroidal boundary conditions. For massless scalar fields and small ellipticity the zero-point energy can be found usin...

2010/12/27
Finite Casimir energies for bosonic fields interacting locally with $N$ objects that do not all have a common intersection are defined by geometrical subtractions. The perturbative expansion for $\be...
A consequence of the repulsive Casimir-Lifshitz force on nano-scale and the related Wheeler propagator in the classical electrodynamics

2010/12/24
Mainly on nano-scale, but maybe not exclusively, it can be imagined a spontaneous charge disjunction inside certain media due to the fluctuations, collisions, wall effects, radiation or/and other pre...
We consider a scattering formulation of radiative momentum transfer to a Magneto-Chiral system
that is subjected to a constant background magnetic field. The system takes the form of a collection mag...

2014/5/28
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 elec...

2014/5/28
We study the polarity of the Casimir force between two different parallel slabs separated by vacuum when the saturated ferrite materials under the influence of an external magnetic field are taken int...

2010/11/4
We comment on progress in measurements of the Casimir force and discuss what is the actual reliability of different experiments. In this connection a more rigorous approach to the usage of such concep...

We study the dynamical Casimir effect in the presence of a finite coherence time, which is associated with a finite quality factor of the optical cavity. We use the time refraction model, where a fixe...

Among the various kinds of effective forces in soft matter, the spatial range and the direction of the so-called critical Casimir force – which is generated by the enhanced thermal fluctuations close ...
