We outline our Lorentz-force approach to the description of dispersion forces (see also C. Raabe and D.-G. Welsch, Phys. Rev. A 71:013814, 2005; Phys. Rev. A 73:063822, 2006). It is based on the ground-state Lorentz force density that acts on the charge and current densities attributed to the polarization and magnetization in linearly, locally, and causally responding media. Application of the theory to dielectric systems yields very general formulas for the Casimir force on dielectric bodies or parts of them. It is shown that well-known expressions for the CasimirPolder force on a single atom and for the van der Waals force between atoms are also contained in our formula. The theory may thus be viewed as providing a unified basis for the calculation of dispersion forces from a macroscopic point of view.

“…We emphasize also that in those cases when the model microscopic analysis does not go beyond the framework of the approximations used in the general theory that was developed above, this analysis reduces in essence only to a microscopic calculation of the dielectric constant. Therefore the use, for example, of the Drude model C 51 " 55 > re ' 86 3 (the model of coupled oscillators) in the derivation of any general formula is, of course, an unnecessary and very rough approximation. At the same time, the use of models to consider some concrete situation, for the purpose of obtaining estimates of the coefficients contained in the general formulas, may turn out to be convenient.…”

A large number of recent articles are devoted to the theory of Van-der-Waals forces between macroscopic bodies, and to a number of related questions. Attention is being paid both to the solution of various concrete problems and to the development of a general theory. The latter is necessitated by the fact that the Van-der-Waals theory of forces between bodies is known to be quite cumbersome. Through certain efforts, the theory expounded in this review has been simplified in certain respects, and was also generalized. The review describes, first, a "simple" theory of Van-der-Waals forces (Chap. 2), which in our opinion is particularly clear and technically simple without adversely affecting the accuracy of the calculations. Second, we develop and describe a rather common and seemingly sufficiently lucid approach, which permits calculation of the contribution of the long-wave equilibrium electromagnetic field and the thermodynamic characteristics of condensed bodies (Chap. 3). Third, results are presented of a number of concrete calculations for Van-der-Waals forces between bodies
