Understanding Axions and Their Role in Dark Matter
Axions are a theoretical elementary particle that play a crucial role in the current understanding of dark matter in cosmology. Proposed in the 1970s as a solution to the strong CP problem in quantum chromodynamics, axions are now being considered as a viable candidate for dark matter. Dark matter constitutes approximately 85% of the universe’s mass and has yet to be directly observed. Researchers believe that axions, though elusive, might be detected through their interactions with ordinary matter, potentially shedding light on some of the universe’s biggest mysteries.
Recent advancements in particle physics have allowed researchers to explore the nature of axions using quasiparticles as proxies. These quasiparticles are emergent excitations in materials that mimic certain properties of axions, allowing scientists to potentially observe signs of dark matter indirectly. Harnessing the unique properties of quantum materials such as manganese bismuth telluride, scientists have set the stage for innovative experiments aimed at confirming the existence of axions and their relationship to dark matter.
