Ultralight Dark Matter Detection with a Ferromagnet Lattice
Dongyi Yang, Xiao Yang, Chenxi Sun +1
A levitated ferromagnet provides an exceptionally sensitive probe of ultralight dark matter (ULDM) through measuring weak magnetic-like field signals. We propose a ferromagnet latt…
Collective response and noise of a levitated ferromagnet lattice for ultralight dark matter detection
Dongyi Yang, Xiao Yang, Chenxi Sun +1
Ultralight dark matter can induce weak oscillating magnetic-like signals and can therefore be searched for with precision magnetometry. Levitated ferromagnets provide a sensitive p…
Boundary-supported radial layering in Hoag-like ring galaxies
Yue Xu, Chenxi Sun, Jianwei Zhang
Clean Hoag-like ring galaxies are often characterized by an old compact central component, a depleted gap, and a detached outer ring. We identify a boundary-supported radial-layeri…
Constraints on Axion Dark Matter by Spin-Dependent Macroscopic Force
Dongyi Yang, Chenxi Sun, Jianwei Zhang
Axion-like particles (ALPs) are hypothetical particles that serve as promising candidates for cold dark matter. Portals like inelastic axion scattering and axion propagated force h…
