DESCRIPTION:Speakers: Yun Jiang(蒋赟) (Sun Yat-sen University)\n\nAbstra
 ct:The standard dynamics of first-order phase transitions (PTs) is driven 
 by bubble nucleation. However\, a low nucleation rate can impede the onset
  of such transitions\, while pre-existing domain walls (DWs) can substanti
 ally alter the PT dynamics. In this talk\, we will discuss a new mechanism
  in which domain walls\, destabilized by thermal fluctuations\, classicall
 y transform into domain trenches of true vacuum\, enabling successful firs
 t-order PT without bubbles. We will also explore its synergy with the alte
 rnative scenario where domain walls\, acting as impurities\, catalyze bubb
 le nucleation\, based on DW dynamics under frictional effects. Biography:
 Dr. Yun Jiang\, tenured Associate Professor\, Ph.D. Supervisor\, School of
  Physics and Astronomy\, Sun Yat-sen University. He received his B.Sc. in 
 Physics from Zhejiang University (2008)\, M.Sc. in High Energy Physics fro
 m the National University of Singapore (2011)\, and Ph.D. in High Energy T
 heory from UC Davis (2015). From 2015 to 2020\, he held postdoctoral posit
 ions at the Niels Bohr Institute (Denmark)\, IFT-UAM (Spain)\, and the Max
  Planck Institute for Nuclear Physics (Germany).His research lies in the f
 rontier between beyond-Standard-Model physics and early-universe particle 
 physics\, particularly Higgs-related cosmology\, the dynamics and lattice 
 simulations of phase transitions and topological defects\, and theoretical
  aspects of thermal field theory. He has published over 40 papers with mor
 e than 4\,000 citations. He also participates as a key member in a Nationa
 l Key Research and Development Project on gravitational waves.Alternative
