Radiation properties of an oscillating atom in the presence of external fields

TL;DR

This paper investigates how external electromagnetic fields and perfect conductors influence the photon emission and decay rates of an oscillating two-level atom, revealing environment-dependent modifications to atomic radiation properties.

Contribution

It provides new theoretical insights into the radiation behavior of oscillating atoms near perfect conductors, considering different configurations and their effects on emission and decay rates.

Findings

Photon emission rate is altered by the presence of perfect conductors.

Decay rate of excited atoms is affected by proximity to conducting surfaces.

Configurations studied show environment-dependent modifications to atomic radiation.

Abstract

In the first part of the present work, the correction to photon emission rate of an oscillating two-level atom in the presence of electromagnetic quantum vacuum field has been investigated for two different configurations: (i) Atom is trapped in the vicinity of a perfect conductor (ii) Atom is trapped between two perfect conductors. In the second part, the correction to the decay rate of an initially excited oscillating two-level atom due to the presence of a perfect conducting surface is found.
