DESCRIPTION:Speakers: Shuailiang Ge（葛帅良） (University of Chicago 
 / KAIST)\n\nAbstract:The nature of dark matter is one of the central quest
 ions shared by particle physics\, astrophysics\, and cosmology. Ultralight
  bosonic dark matter\, represented by QCD axions\, axion-like particles\, 
 and dark photons\, is strongly motivated theoretically. It can behave as a
  classical wave field in the Universe\, giving rise to detection signals t
 hat are distinct from those of conventional particle dark matter. This tal
 k will introduce the theoretical foundations of ultralight dark matter\, s
 everal detection ideas\, and its cosmological implications. First\, I will
  discuss the interactions of ultralight dark matter with media such as met
 al antennas and plasmas\, and introduce how large astronomical facilities\
 , including FAST\, LOFAR\, and Parker Solar Probe\, can be used to search 
 for ultralight dark matter. Second\, I will discuss topological defects su
 ch as cosmic strings and domain walls produced in axion models in the earl
 y Universe\, and explain how they can generate observable relics such as s
 tochastic gravitational-wave backgrounds and primordial black holes. Final
 ly\, I will discuss future opportunities in the theory and detection of ul
 tralight dark matter.Alternative online link: https://meeting.tencent.com
