Cavity fields boundaries

IS added to the short-range molecule-molecule interaction. Problems with the reaction ethod may arise from discontinuities in the energy and/or force when the number of les j rvithin the cavity of the molecule i changes. These problems can be avoided by dng a switching function for molecules that are near the reaction field boundary. 

The OWB equations obtained in this semiclassical scheme analyse the effective polarizabilities in term of solvent effects on the polarizabilities of the isolated molecules. Three main effects arise due to (a) a contribution from the static reaction field which results in a solute polarizability, different from that of the isolated molecules, (b) a coupling between the induced dipole moments and the dielectric medium, represented by the reaction field factors FR n, (c) the boundary of the cavity which modifies the cavity field with respect the macroscopic field in the medium (the Maxwell field) and this effect is represented by the cavity field factors /c,n. 

One of the first estimations of the number of photons that could be created from vacuum in a cavity whose boundary moves with nonrelativistic velocity have been performed by Rivlin [113], who considered the parametric amplification of the initial vacuum field oscillations in the framework of the classical approach. He estimated the number of created photons Jf (eooit)2, where e 8L/L is the relative amplitude of the variation of the distance between the...
