Detecting dark matter using optically trapped Rydberg atom tweezer arrays
So Chigusa, Taiyo Kasamaki, Toshi Kusano +6
A new scheme for detecting wave-like dark matter (DM) using Rydberg atoms is proposed. Recent advances in trapping and manipulating Rydberg atoms make it possible to use Rydberg at…

Interplay of ALP Couplings at a Muon Collider
So Chigusa, Sudhakantha Girmohanta, Yuichiro Nakai +1
Axion-like particles can couple to Standard Model gluons, electroweak gauge bosons, and massive fermions. A future multi-TeV muon collider provides a favorable environment to probe…

Light Dark Matter Search with Nitrogen-Vacancy Centers in Diamonds
So Chigusa, Masashi Hazumi, Ernst David Herbschleb +2
We propose new ideas to directly search for light dark matter, such as the axion or the dark photon, by using magnetometry with nitrogen-vacancy centers in diamonds. If the dark ma…
