چکیده
casimir forces of massive ferrnionic dirac fields are calculated for parallel plates geometry in spatial space with dimension d and imposing bag model boundary conditions. it is shown that in the range of ma>>l where m is mass of fields quanta and a is the separation distance of the plates, it is equal to massive bosonic fields casimir force for each degree of freedom. we argue this equality exists for any massive anyonic field in two-dimensional spatial space. also the ratio of massless ferrnionic field casimir force to its bosonic correspondent in d-dimensional spatial spaceis (1- )

متن کاملScreened Casimir forces
We demonstrate that a very recently obtained formula for the force on a slab in a material planar cavity based on the calculation of the vacuum Lorentz force [C. Raabe and D.-G. Welsch, Phys. Rev. A, 71, 013814 (2005)] describes a (medium) screened Casimir force and, in addition to it, a medium-assisted force. The latter force also describes the force on the cavity medium. For dilute media, it ...
متن کاملMedium-modified Casimir forces
Abstract. We argue that the results for the vacuum forces on a slab and on an atom embedded in a magnetodielectric medium near a mirror, obtained using a recently suggested Lorentz-force approach to the Casimir effect, are equivalent to the corresponding results obtained in a traditional way. We also derive a general expression for the atom-atom force in a medium and extend a few classical resu...
متن کاملCasimir forces on a silicon micromechanical chip.
Quantum fluctuations give rise to van der Waals and Casimir forces that dominate the interaction between electrically neutral objects at sub-micron separations. Under the trend of miniaturization, such quantum electrodynamical effects are expected to play an important role in micro- and nano-mechanical devices. Nevertheless, utilization of Casimir forces on the chip level remains a major challe...
متن کاملCasimir Forces in Chiral Metamaterials
We use the extended Lifshitz theory to study the behavior of the Casimir forces between chiral metamaterials and regular metamaterials. We have shown that the chirality, if strong enough, is of critical importance to reduce the Cassimir attractive force and can find new designs to obtain repulsive Casimir forces. We will review chiral metamaterials and find some analytical expression for the st...
