Coherence from Randomness: Sub-keV Dark Matter Scattering off Random, Heterogeneous Materials
Zhi-Han Liu, Shigeki Matsumoto, Jie Sheng +1
The sub-keV mass range has long posed a challenge for the direct detection of dark matter via elastic scattering. In this Letter, we propose a new mechanism in which dark matter, a…
Torsion Balance Experiments Enable Direct Detection of Sub-eV Dark Matter
Shigeki Matsumoto, Jie Sheng, Chuan-Yang Xing +1
Light dark matter with sub-eV masses has a high number density in our galaxy, and its scattering cross section with macroscopic objects can be significantly enhanced by coherence e…
Detecting the Coupling of Axion Dark Matter to Neutron Spins at Spallation Sources via Rabi Oscillation
Peter Fierlinger, Jie Sheng, Yevgeny V. Stadnik +1
We propose a novel detection method for axion dark matter using the Rabi oscillation of neutron spins in beam-based measurements. If axions couple to neutron spins, a background os…
Detecting meV-Scale Dark Matter via Coherent Scattering with an Asymmetric Torsion Balance
Pengshun Luo, Shigeki Matsumoto, Jie Sheng +3
Dark matter with mass in the crossover range between wave dark matter and particle dark matter, around eV, remains relatively unexplored by terrestrial experim…
