Vacuum Fluctuations and the Casimir Force
نویسنده
چکیده
The Casimir Force was predicted in 1948 by Dutch physicist Hendrick Casimir. Casimir realized that when calculating the energy between two parallel uncharged conducting plates, only those virtual photons whose wavelengths fit an integral number of times into the gap should be counted. Each mode contributes to a pressure on the plates, and the infinite number of modes outside the plates is in some sense greater than the infinite number inside the plates, resulting in a small force drawing the plates together. This experimentally-confirmed force is one observable consequence of the existence of the vacuum electromagnetic field.

The Casimir attraction can significantly interfere the physical response of nanoactuators. The intensity of the Casimir force depends on the geometries of interacting bodies. The present paper is dedicated to model the influence of the Casimir attraction on the electrostatic stability of nanoactuators made of cylindrical conductive nanowire/nanotube. An asymptotic solution, based on path-integr...

Vacuum fluctuations have observable consequences, like the Casimir force appearing between two mirrors in vacuum. This force is now measured with good accuracy and agreement with theory. We discuss the meaning and consequences of these statements by emphasizing their relation with the problem of vacuum energy, one of the main unsolved problems at the interface between gravitational and

It is well known that nothing comes from nothing. In physics, however, this is not always the case. Surprisingly indeed, two electrically neutral conducting metallic plates placed in vacuum about half a micrometer apart attract each other, even at zero temperature, due to a force which was theoretically predicted in 1948 by the Dutch physicist Hendrik Casimir [1]. This force originates from the...
متن کاملLong-range magnetic interaction due to the Casimir effect.
The zero-point quantum fluctuations of the electromagnetic field in vacuum are known to give rise to a long-range attractive force between metal plates (Casimir effect). For ferromagnetic layers separated by vacuum, it is shown that the interplay of the Casimir effect and of the magneto-optical Kerr effect gives rise to a long-range magnetic interaction. The Casimir magnetic force is found to d...
