Researchers are using quantum technologies to develop sensitive dark matter detectors, focusing on two likely candidates: weakly interacting particles and axions. The technology involves superfluid helium-3 and quantum amplifiers. Credit: SciTechDaily.com
The researchers include Dr. Michael Thompson, Professor Edward Laird, Dr. Dmitry Zmeev, and Dr. Samuli Autti from Lancaster, Professor Jocelyn Monroe from Oxford, and Professor Andrew Casey from RHUL. Particle physics theory suggests two likely dark matter candidates: new particles with interactions so weak we haven’t observed them yet, and, very light wave-like particles termed axions. The team is building two experiments, one to search for each.
Demonstrating how we infer dark matter from observing galaxies, there will be a gyroscope-in-a-box that moves in surprising ways due to the unseen angular momentum. There will also be glass marbles that are transparent in liquid, showing how invisible masses may be observed using clever experimentation.

Searching for dark matter with the coldest quantum detectors in the worldOne of the greatest mysteries of science could be one step closer to being solved. Approximately 80% of the matter in the universe is dark, meaning that it cannot be seen. In fact, dark matter is passing through us constantly—possibly at a rate of trillions of particles per second.
