# Thermal effects in the magnetic Casimir-Polder interaction

## TL;DR

This paper studies how thermal effects influence the magnetic Casimir-Polder interaction between an atom and a metallic surface, revealing a repulsive correction sensitive to material dissipation.

## Contribution

It provides new insights into the thermal magnetic Casimir-Polder interaction, emphasizing the role of Ohmic dissipation in the material.

## Key findings

- Thermal effects induce a repulsive correction in the magnetic Casimir-Polder interaction.
- The interaction's magnitude depends on the Ohmic dissipation in the metallic surface.
- Magnetic interactions differ from electrical ones in their sensitivity to material dissipation.

## Abstract

We investigate the magnetic dipole coupling between a metallic surface and an atom in a thermal state, ground state and excited hyperine state. This interaction results in a repulsive correction and - unlike the electrical dipole contribution - depends sensitively on the Ohmic dissipation in the material.
