Enhanced Radiation ? from (Super) Conductor by Dark Matter Axion

TL;DR

This paper reevaluates the claim that dark matter axions can enhance radiation from superconductors under magnetic fields, concluding that the radiation is not enhanced but reflected, clarifying the electromagnetic interaction.

Contribution

The paper provides a revised calculation showing that axion-induced radiation from conductors is not enhanced, emphasizing the reflection mechanism over amplification.

Findings

Radiation from conductors by axions is not enhanced.

Reflected wave amplitude equals the incident wave amplitude.

Electromagnetic field induced by axions is reflected by the conductor.

Abstract

In our previous paper we have shown that enhanced radiations arise from (super) conductor by dark matter axion under strong magnetic field. We have recalculated the radiation by carefully treating boundary conditions between vacuum and the conductor. We show that the radiation is never enhanced. We interpret it such that electromagnetic field induced by axion collides the conductor and it is reflected by the conductor. The reflecting wave is the radiation from the conductor. It is reasonable that the amplitude of the reflection wave is identical to that of the incoming wave, i.e. radiation induced by axion.
