Atomic Quantum Sensors for High-Frequency Gravitational Wave Searches
Yi-fu Cai, Luca Visinelli, Sheng-Feng Yan
High-frequency gravitational waves (GWs), spanning frequencies from the microwave to the optical band, remain experimentally unexplored despite strong motivation from early-Univers…
Transient axion streams from disrupted miniclusters
Luca Visinelli, Momchil Naydenov
We investigate the formation and evolution of axion streams generated by the tidal disruption of axion miniclusters through stellar encounters in the Milky Way halo. Combining a la…
Direct detection of solar chameleons with electron recoil data from XENONnT
Guan-Wen Yuan, Anne-Christine Davis, Maurizio Giannotti +3
We reassess prospects for direct detection of solar chameleons, in light of recent progress in modeling their production, and the availability of new XENONnT data. We show that the…
Axions as Dark Matter, Dark Energy, and Dark Radiation
Luca Visinelli
Axions and axion-like particles are ubiquitous in extensions of the Standard Model and offer a unifying framework for addressing open problems in cosmology. Depending on their mass…
Microscopic primordial black holes as macroscopic dark matter from large extra dimensions
Giuseppe Filiberto Vitale, Gaetano Lambiase, Tanmay Kumar Poddar +1
We study the coupled cosmological evolution of primordial black holes (PBHs) and radiation in the Arkani-Hamed-Dimopoulos-Dvali (ADD) framework with large extra dimensions and…
Probing Solar Symmetrons with Direct Detection
Hannah Banks, Anne-Christine Davis, Luca Visinelli
We provide the first investigation of the solar production of symmetrons, a well-motivated class of screened scalar fields with density dependent couplings to the Standard Model, a…
