The axion quasiparticle forms when the interaction between the electric field and magnetization oscillates in a specific pattern over time.
Scientists may have found an imitation form for one of physics’ hypothetical and most elusive particles — the axion.Long considered a missing piece in the puzzle of dark matter , the axion has remained out of reach — until now.In a breakthrough experiment, researchers from Harvard and King’s College London have created a convincing imitation of the particle within a thin sheet of material, offering physicists a powerful new way to study the axion’s elusive behavior.
The researchers created a quasiparticle by using a laser to generate a magnon, a magnetic wave that travels through the material.This wall is followed by employing another laser to probe the material’s magnetization. This uncovered an oscillation in the interaction between the electric field and magnetization over time, which is defining characteristic of an axion.
