Dynamical Casimir-Polder Force between a Metallic Particle and a Perfectly Conducting Plate

TL;DR

This paper investigates how the magnetic polarizability of a metallic particle affects the dynamical Casimir-Polder force when the particle moves at relativistic speeds near a perfect conductor, using the Drude model.

Contribution

It introduces the first analysis of magnetic polarizability effects on the dynamical Casimir-Polder force for relativistically moving particles near conducting surfaces.

Findings

Magnetic polarizability significantly influences the Casimir-Polder force.

Relativistic motion alters the force magnitude and direction.

Material properties modeled with the Drude approach are crucial for accurate predictions.

Abstract

For the first time, we have studied the impact of magnetic polarizability of a neutral metallic particle on the dynamical Casimir-Polder force, when the particle is uniformly moving with relativistic velocity parallel to the surface of an ideally conducting plate. The material properties of particle are taken into account within the Drude model approach.
