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.…
Refined Sensitivity Estimates for Single-Molecule Magnet Dark Matter Detectors
Andrew Eberhardt, Tomoya Fukui, Ryosuke Takehara +8
We revisit the sensitivity of Single Molecule Magnet (SMM) crystals as detectors for low-mass dark matter. In previous work, we established the concept of the ``magnetic bubble cha…
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…
JFlow: Model-Independent Spherical Jeans Analysis using Equivariant Continuous Normalizing Flows
Sung Hak Lim, Kohei Hayashi, Shun'ichi Horigome +2
The kinematics of stars in dwarf spheroidal galaxies have been studied to understand the structure of dark matter halos. However, the kinematic information of these stars is often…
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 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…
