Earth Matter Enhanced Axion Dark Matter Search
Xiaofei Huang, Xiaolin Ma, Zitong Xu +2
Laboratory searches for ultralight axion dark matter (DM) have traditionally assumed the terrestrial density of axions is equal to the average density of DM in the solar system. Ho…
Search for a parity-violating long-range spin-dependent interaction
Xing Heng, Zitong Xu, Xiaofei Huang +6
High-sensitivity quantum sensors are a promising tool for experimental searches for beyond-Standard-Model interactions. Here, we demonstrate an atomic comagnetometer operating unde…
Dark Matter Search with a Resonantly-Coupled Hybrid Spin System
Kai Wei, Zitong Xu, Yuxuan He +9
Recent advances in tabletop quantum sensor technology have enabled searches for nongravitational interactions of dark matter (DM). Traditional axion DM experiments rely on sharp re…
New Constraints on Axion Mediated Dipole-Dipole Interactions
Zitong Xu, Xing Heng, Guoqing Tian +5
The search for axions sits at the intersection of solving critical problems in fundamental physics, including the strong CP problem in QCD, uncovering the nature of dark matter, an…
