DW-genesis: baryon number from domain wall network collapse
Alberto Mariotti, Xander Nagels, Aäron Rase +1
Axionic domain walls, as they move through the early universe plasma during their collapse, can generate a net baryon and lepton number through the mechanism of spontaneous baryoge…
Populating secluded dark sector with ultra-relativistic bubbles
Aleksandr Azatov, Xander Nagels, Miguel Vanvlasselaer +1
We study Dark Matter production during first order phase transitions from bubble-plasma collisions. We focus on scenarios where the Dark Matter sector is secluded and its interacti…
Criterion for ultra-fast bubble walls: the impact of hydrodynamic obstruction
Wen-Yuan Ai, Xander Nagels, Miguel Vanvlasselaer
The Bödeker-Moore thermal friction is usually used to determine whether or not a bubble wall can run away. However, the friction on the wall is not necessarily a monotonous functio…
Bubble-assisted Leptogenesis
Eung Jin Chun, Tomasz P. Dutka, Tae Hyun Jung +2
We explore the possibility of embedding thermal leptogenesis within a first-order phase transition (FOPT) such that RHNs remain massless until a FOPT arises. Their sudden and viole…
