Laser-assisted interaction between nonrelativistic electrons and positrons

TL;DR

This paper theoretically investigates how intense electromagnetic radiation influences the interaction between nonrelativistic electrons and positrons, revealing conditions under which they experience effective attraction and asymmetry in their interactions.

Contribution

It introduces a theoretical model accounting for electromagnetic field effects and relativistic corrections on nonrelativistic charged particles, highlighting potential effective attraction mechanisms.

Findings

Electromagnetic radiation can induce effective attraction between same-charged particles.

Trajectory analysis shows particles align and approach each other under intense waves.

Asymmetry observed in attraction between electrons and positrons.

Abstract

The effective interaction between two classical nonrelativistic electrons (positrons) in the presence of intense electromagnetic radiation (one and two waves) is theoretically studied. Small relativistic corrections are taking into account in the laboratory reference frame. The field of an intense wave forms the movement of particles in such a way that their trajectories are practically parallel for quite a long time, and in the perpendicular direction the particles shift slightly, approaching first and then moving away from each other. This result can be considered as an effective attraction of same charged particles. Shown that the effective attraction of two electrons and two positrons could be substantially asymmetric.
