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…
