The Primakoff effect is a quantum mechanical phenomenon where a neutral particle, like a photon, can convert into another neutral particle, such as an axion or a weakly interacting massive particle (WIMP), in the presence of an external electromagnetic field. This effect is significant in experimental searches for dark matter candidates and helps to explore the properties of these elusive particles through quantum sensors. Understanding this conversion process is essential in identifying the characteristics and interactions of axions and WIMPs.
