Numerical Estimations of the Distribution of the Lifetime of Bubbles Emerging from First Order Cosmological Phase Transitions
Mulham Hijazi
We present a mathematical framework to produce a numerical estimation to the distribution of the lifetime of bubbles emerging from first order cosmological phase transitions. In a…
Frictionless UV-finite Instantons in Curved Spacetime
Mulham Hijazi, Apostolos Pilaftsis
We identify a new class of UV-complete instanton solutions that describe the false vacuum\- decay of a real scalar field in a particular curved spacetime background. To this end, w…
Goldstone Boson Effects on Vacuum Decay
Mulham Hijazi, Apostolos Pilaftsis
We study the effects of Goldstone modes on the stability of the vacuum in a theory for a complex scalar field. The dynamics of the field resemble those of Keplerian motion i…
Gravitational waves from first order cosmological phase transitions in the Sound Shell Model
Mark Hindmarsh, Mulham Hijazi
We calculate gravitational wave power spectra from first order early Universe phase transitions using the Sound Shell Model. The model predicts that the power spectrum depends on t…
