Enhanced Rydberg-Atom Superheterodyne Detection of Hidden-Photon Dark Matter on Chips
Xiaochen Li, Bo Gao, Shigeki Matsumoto +3
Although hidden-photon dark matter with masses above is well motivated by inflationary production, it remains largely unexplored by terrestrial experiments.…
Macroscopic Quantum Interference in Dark Matter Wave Scattering with MICROSCOPE
Cheng-Tao Fu, Peng-Shun Luo, Rui Luo +2
Ultralight dark matter behaves as a coherent wave, yet its quantum interference effects of elastic scattering with multiple targets have remained unexplored. We show that the neste…
Enhanced Dark Matter Quantum Sensing via Geometric Phase
Xiaolin Ma, Jie Sheng
We propose a quantum sensing protocol for coupled qubit-oscillator systems that surpasses the standard quantum limit by exploiting a geometric phase for dark matter searches. Inste…
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…
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…
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…
