The meaning of VAN DER WAALS FORCES is the relatively weak attractive forces that act on neutral atoms and molecules and that arise because of the electric polarization induced in each of the particles by the presence of other particles.
There are different formulas for calculating the van der Waals interaction force between two bodies, depending on their geometry. Each of these formulas is the product of two terms; one is a geometric term which depends only on the shape and separation distance of the interacting bodies, and ...
Velocity dependence of the van der Waals force between molecules It is shown that the van der Waals interaction between two molecules in relative motion depends on the relative velocity. The velocity-dependent correction... Mahanty,J - 《Journal of Physics B Atomic & Molecular Physics》 被引量...

We consider the van der Waals interaction between two ground-state atoms embedded in adjacent semi-infinite magnetodielectric media, with emphasis on medium effects on it. We demonstrate that, in this case, at small atom-atom distances the van der Waals interaction is screened by the surrounding...
