Probing Collapsed Dark Matter Halos with Fast Radio Bursts
Yuxuan He, Weiyang Wang, Chen Zhang +1
Observations of ultra-dense substructures in strong lensing systems challenge the standard cosmological model at small scales. Self-interacting dark matter (SIDM), as an alternativ…
Implications of the KM3NeT Ultrahigh-energy Event on Neutrino Self-interactions
Yuxuan He, Jia Liu, Xiao-Ping Wang +1
Neutrino self-interactions (SI) mediated by light bosonic particles can produce characteristic spectral dips in astrophysical neutrino fluxes, thereby altering the expected ene…
Dark Matter Search with a Resonantly-Coupled Hybrid Spin System
Kai Wei, Zitong Xu, Yuxuan He +9
Recent advances in tabletop quantum sensor technology have enabled searches for nongravitational interactions of dark matter (DM). Traditional axion DM experiments rely on sharp re…
Particle Conversions Beyond the WKB Approximation and Solar-Induced Gravitational Waves from Dark Photon Dark Matter
Tengyu Ai, Yuxuan He, Jia Liu +2
We investigate the conversion of kinetic mixing dark photon dark matter into gravitational waves within the magnetic field of the Sun. Our study reveals that the WKB approximation…
