Fluctuation induced forces in critical films with disorder at their surfaces

Fluctuation-Induced Structural Forces in Nematic Films

Fluctuation - induced forces in critical fluids

The current knowledge about fluctuation induced long-ranged forces is summarized. Reference is made in particular to fluids near critical points, for which some new insight has been obtained recently. Where appropiate, results of analytic theory are compared with computer simulations and experiments.

THE CRiTiCaL CaSimiR EFFECT UNIVERSAL FLUCTUATION - INDUCED FORCES aT WORk

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...

Vacuum fluctuation forces between ultra-thin films

We have investigated the role of the quantum size effects in the evaluation of the force caused by electromagnetic vacuum fluctuations between ultra-thin films, using the dielectric tensor derived from the particle in a box model. Comparison with the results obtained by adopting a continuum dielectric model shows that, for film thicknesses of 1÷10 nm, the electron confinement causes changes in ...
