DESCRIPTION:Speakers: Ke-Pan Xie（谢柯盼） (Beihang University)\n\nAb
 stract:  The process of symmetry breaking in the early Universe can mani
 fest as a first-order phase transition (FOPT)\, a second-order phase trans
 ition\, or a smooth crossover. If the breaking proceeds via a FOPT\, the u
 nique vacuum bubble nucleation structure and out-of-equilibrium environmen
 t can provide the necessary conditions for matter-antimatter asymmetry gen
 eration and dark matter formation\, and may even produce primordial black 
 holes or a multiverse. This talk will describe the principles of FOPTs\, i
 ntroduce recent progress in new physics mechanism study\, and discuss the 
 corresponding phenomenological signals\, including gravitational waves and
  collider signatures. About the speaker:  Ke-Pan Xie is an associate pr
 ofessor at Beihang University. He received his B.S. from Zhejiang Universi
 ty in 2013 and his Ph.D. from Peking University in 2018. He subsequently c
 onducted postdoctoral research at Seoul National University in South Korea
  and the University of Nebraska-Lincoln in the United States before joinin
 g Beihang University in 2022. His research focuses on theoretical particle
  physics\, with particular emphasis on the search for new physics beyond t
 he Standard Model\, including particle cosmology and collider phenomenolog
 y. He has published over 40 papers in SCI-indexed journals. Online Meetin
