The Quantum Quest for Dark Matter’s Elusive Axion Particle

Posted by in categories: cosmology, particle physics, quantum physics

Aalto University researchers will probe the secrets of dark matter using a quantum detector of unprecedented sensitivity.

In the vast darkness of the cosmos lurks an invisible kind of matter. Its presence is seen in the rippling ebb and flow of galaxies, but it’s never been directly observed. What secrets lie beneath the surface, brewing in the deep?

Physicists have long theorized about the composition of dark matter, which is thought to be five times more abundant than regular matter. Among competing hypotheses, one particle has emerged as a promising candidate: the axion.
