Mixing of photons with light pseudoscalars in time-dependent magnetic fields

TL;DR

This paper investigates how a time-dependent magnetic field can increase the conversion probability of photons into axion-like particles, potentially improving detection methods in experimental physics.

Contribution

It introduces a model analyzing photon-axion conversion in dynamic magnetic fields, revealing conditions that enhance conversion amplitude compared to static fields.

Findings

Time-dependent magnetic fields can increase axion-like particle production.

Conversion probability is significantly enhanced in certain time regimes.

Dynamic fields offer a promising avenue for axion detection experiments.

Abstract

The effects of an external time-dependent magnetic field in the conversion probability of photon-to-axion-like particles are studied. Our findings show that for a certain time regime, the amplitude of the produced axion-like field can be enlarged with respect to the static case, thus, enhancing the probability of conversion.
