DESCRIPTION:Speakers: Yun Jiang\n\nAbstract: First-order phase transitions
  (PTs) are conventionally driven by the nucleation of true-vacuum bubbles.
  However\, a low nucleation rate can suppress the onset of PTs\, while pre
 -existing domain walls (DWs) can significantly modify the PT dynamics. In 
 this talk\, we present a mechanism in which domain walls\, destabilized by
  thermal fluctuations\, classically transform into domain trenches of true
  vacuum\, thereby enabling a successful first-order PT in the absence of b
 ubble formation. We discuss the implementation of thermal fluctuations on 
 the lattice and provide simulation results. Furthermore\, we examine DW dy
 namics under frictional effects and explore its interplay with an alternat
 ive scenario in which domain walls act as impurities that catalyze bubble 
 nucleation. 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.S
 c. in High Energy Physics from the National University of Singapore (2011
 )\, and Ph.D. in High Energy Theory from UC Davis (2015). From 2015 to 202
 0\, he held postdoctoral positions at the Niels Bohr Institute (Denmark)\,
  IFT-UAM (Spain)\, and the Max Planck Institute for Nuclear Physics (Germ
 any). His research lies in the frontier between beyond-Standard-Model phy
 sics and early-universe particle physics\, particularly Higgs-related cosm
 ology\, the dynamics and lattice simulations of phase transitions and topo
 logical defects\, and theoretical aspects of thermal field theory. He has 
 published over 40 papers with more than 4\,000 citations. He also particip
 ates as a key member in a National Key Research and Development Project on
  gravitational waves. Online Link: Join Zoom Meetinghttps://caltech.zoom.
