Seeded bubble nucleation on the lattice
Simone Blasi, Andreas Ekstedt, Jaakko Hällfors +1
We provide the first non-perturbative lattice determination of the bubble nucleation rate as seeded by topological defects during a first order phase transition. Our case of study…
Slow-down of expanding bubbles in the early Universe
Nabeen Bhusal, Simone Blasi, Thomas Konstandin +2
We study slow-down effects for bubbles formed in a cosmological first-order phase transition (PT) focusing on deflagrations and hybrids, where the bubble wall is preceded by a shoc…
Domain walls in the scaling regime: Equal Time Correlator and Gravitational Waves
Simone Blasi, Alberto Mariotti, Aäron Rase +1
Domain walls are topological defects that may have formed in the early Universe through the spontaneous breakdown of discrete symmetries, and can be a strong source of gravitationa…
Cosmological and High Energy Physics implications from gravitational-wave background searches in LIGO-Virgo-KAGRA's O1-O4a runs
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1771
We search for gravitational-wave background signals produced by various early Universe processes in the Advanced LIGO O4a dataset, combined with the data from the earlier O1, O2, a…
Gravitational waves from the sound shell model: direct and inverse phase transitions in the early Universe
Giulio Barni, Simone Blasi, Eric Madge +1
Cosmological phase transitions are a frequent phenomenon in particle physics models beyond the Standard Model, and the corresponding gravitational wave signal offers a key probe of…
Standard Model Baryon Number Violation at Zero Temperature from Higgs Bubble Collisions
Nabeen Bhusal, Simone Blasi, Martina Cataldi +3
We compute for the first time baryon number violation at zero temperature from Higgs bubble collisions and find that it can be of the same order as that from thermal sphalerons in…
Inverse bubbles from broken supersymmetry
Giulio Barni, Simone Blasi, Miguel Vanvlasselaer
Building upon the recent findings regarding inverse phase transitions in the early universe, we present the first natural realisation of this phenomenon within a supersymmetry-brea…
The hydrodynamics of inverse phase transitions
Giulio Barni, Simone Blasi, Miguel Vanvlasselaer
First order phase transitions are violent phenomena that occur when the state of the universe evolves abruptly from one vacuum to another. A \emph{direct} phase transition connects…
