DESCRIPTION:Speakers: Yu HAMADA (University of Osaka)\n\nAbstract: Domain
  wall (DW) networks may have formed in the early universe following the sp
 ontaneous breaking of a discrete symmetry. Several BSM models predict the 
 existence of current-carrying DWs\, which can capture and store particles 
 as localized zero modes. In this work\, we show that gravitational wave (G
 W) generated by current-carrying DWs with fermionic zeromodes exhibit an a
 dditional peak in the GW spectrum arising from metastable remnants. This s
 ignature could be detectable in upcoming GW observatories such as LISA. Th
 e results suggest that DW networks could emit GW signals that are signific
 antly stronger and with greater detectability than previously expected. B
 iography: Yu HAMADA  received his Doctor of Science from Kyoto Universi
 ty in 2021. He was a JSPS Postdoctoral Fellow at KEK from 2021 to 2023 and
  at DESY from 2023 to 2026. Since 2026\, he has been an Assistant Professo
 r at The University of Osaka. His research focuses on particle phenomenolo
 gy and cosmology\, including topological defects\, gravitational waves. He
  has authored 32 research publications to date and has received several aw
 ards\, including "Particle Physics Medal: Young Scientist Award in Theoret
 ical Particle Physics" in 2023 and "Young Scientist Award of the Physical 
 Society of Japan" in 2025.\n\nhttps://indico-tdli.sjtu.edu.cn/event/4995/
