Search for Ultralight Axion Dark Matter with a Levitated Ferromagnetic Torsional Oscillator
Chunlong Li, Yiwei Huang, Shien Yang +5
We present a search for ultralight axion dark matter coupled to electron spins using a levitated ferromagnetic torsional oscillator (FMTO). This platform directly measures axion-in…
Constraints on Velocity and Spin Dependent Exotic Interaction at the Millimeter Scale with a Diamagnetic-levitated Force Sensor
Kenan Tian, Yuanji Sheng, Rui Li +8
Light bosons, beyond the standard model and as prominent candidates for dark matter, can mediate velocity and spin dependent exotic interaction between electron spins and nucleons.…
Search of High-Frequency Variations of Fundamental Constants Using Spin-based Quantum Sensors
Xi Kong, Yuke Zhang, Chenyu Ji +6
This study presents a novel method using spin quantum sensors to explore temporal variations of fundamental constants, significantly expanding the frequency range and providing con…
A rotational ellipsoid model for solid Earth tide with high precision
Yongfeng Yang, Yunfei Zhang, Qiang Liu +2
Solid Earth tide represents the response of solid Earth to the lunar (solar) gravitational force. The yielding solid Earth due to the force has been thought to be a prolate ellipso…
