Van der Waals forces and spatial dispersion
L. P. Pitaevskii
TL;DR
This paper presents a Green's functions approach to Van der Waals forces incorporating spatial dispersion, based on the fluctuation-dissipation theorem, applicable to bodies separated by vacuum, and discusses objections to existing theories with spatial dispersion.
Contribution
It introduces a Green's functions framework for Van der Waals forces that accounts for spatial dispersion, enhancing theoretical modeling capabilities.
Findings
Valid for interacting bodies separated by vacuum
Based on fluctuation-dissipation theorem
Addresses objections to spatial dispersion theories
Abstract
A version of the Green's functions theory of the Van der Waals forces which can be conveniently used in the presence of spatial dispersion is presented. The theory is based on the fluctuation-dissipation theorem and is valid for interacting bodies, separated by vacuum. Objections against theories acounting for the spatial dispersion are discussed.
