Center for Axion and
Precision Physics Research

Yun is developing a new magnetometry experiment to search for axion-like spin-dependent interactions between nuclei at sub-millimeter ranges in ARIADNE collaboration. The experiment involves a rotating non-magnetic mass to source the axion field, and a dense gaseous ensemble of laser-polarized 3He nuclei to detect the axion field by NMR. Yun is also working on a novel experimental scheme enabling the investigation of transient exotic spin couplings to stable topological defects (e.g., domain walls) of axion-like fields with collaboration in GNOME project.
