SUMMARY:Pheno Journal Club: 'Bubble Nucleation from Boson Star Collapse'
DESCRIPTION:Title: Bubble Nucleation from Boson Star Collapse\n\nSpeaker: Kateryna Radchenko Serdula (IFT) will present “Bubble Nucleation from Boson Star Collapse”\, 2511.21826\n\nVenue&Time: Gray Room 2 / 12:00\n\nAbstract: We present a new classical mechanism for nucleation of bubbles of true vacuum. The mechanism arises when dense boson stars form in the false vacuum. As the boson stars collapse due to attractive self-interactions\, the field inside the star cores is enhanced beyond the potential barrier. Subsequently the stars explode as true vacuum bubbles and induce a cosmological phase transition. The mechanism raises the possibility that a vacuum that is stable against quantum tunneling can be vulnerable to “astrophysical” processes.\n
