  1. 59. Determining the Nature of Dark Matter with Astronomical Observations: Dwarf Galaxies and Small-Scale Structure
    效军 毕 (中科院高能所)
    17/04/2026, 13:30

    Despite decades of intensive direct detection searches across different dark matter candidates, no conclusive particle signal has been identified. This motivates complementary constraints on dark matter properties model independently from astronomical observations. In this talk, we focus on wave-like ultralight dark matter (ULDM) and its dynamical impact on dwarf galaxies. We will show that...

  3. 7. High sensitivity magnetometry with ferromagnetic spins and its applications in fundamental physics
    Wei Ji (Peking University)
    17/04/2026, 14:30

    Due to their high spin density and low spin projection noise, ferromagnetic systems are expected to be powerful tools for high-precision metrology. This presentation will discuss our recent investigations into physics beyond the Standard Model, utilizing ferromagnetic spins as a platform."
