Dispersion interaction between two atoms in electromagnetic fields

TL;DR

This paper develops a new theoretical framework for understanding how electromagnetic fields influence the dispersion interactions between two atoms, including effects from virtual photon exchange and resonance in non-equilibrium conditions.

Contribution

The paper introduces a novel theory that incorporates absorption, emission, and resonance effects in atom-atom dispersion interactions under electromagnetic fields.

Findings

New theoretical model for atom-atom interactions in electromagnetic fields

Accounts for virtual photon processes and resonance contributions

Applicable to non-equilibrium atomic dynamics

Abstract

We present a new theory of atom-atom dispersion interaction in the presence of electromagnetic fields. The theory takes into account the absorption and emission of virtual photons leading to the resonance contributions to the interaction potential in the case of non-equilibrium dynamics.
