Unleashing the Power of Ultra-Precise Atomic Clocks in Dark Matter Research

Scientists are using atomic clocks to investigate the nature of dark matter and search for new physics beyond the Standard Model. Atomic clocks measure time using atoms with two energy states, and any variation in their resonance frequencies could indicate the presence of ultra-light particles associated with dark matter. By comparing two clocks, one sensitive to changes in fundamental constants and the other less sensitive, researchers can set constraints on these particles. This technique could also potentially be used to study dark energy. The results of this research are set to be published in the New Journal of Physics.

Sensitive Laser Experiment Searches for Dark Matter Particles

The ALPS II experiment, designed to detect axionic dark matter, could expose particles responsible for dark matter. The experiment involves a wall that light cannot pass through, but an axion could. If light shows up on the far side of the experiment, it would indicate that a photon turned into an axion, transitted the wall, and reverted to a photon. The experiment will begin its search in an “attenuated operating mode” and is expected to reach full sensitivity later this year. The first data from the experiment is expected in 2024.
