Effective field theory for strong phase transitions
Oliver Gould, Farbod-Sayyed Rassouli, Paul M. Saffin
We show how to construct perturbative effective field theories for strong phase transitions, where the standard tools of high-temperature dimensional reduction fail. By identifying…
Quantum fields in boson star spacetime
Paul M. Saffin, Qi-Xin Xie
Boson stars have been extensively studied in classical gravity, but their quantum properties remain comparatively unexplored. In this paper, we compute the quantum scalar fields an…
Matter Sourced Bubble Nucleation in the Asymmetron Scalar-Tensor Theory
Usama Syed Aqeel, Clare Burrage, Oliver Gould +1
We investigate how matter density distributions affect thin-wall bubble formation in the asymmetron mechanism, a scalar-tensor theory with a universal coupling to matter and explic…
Oscillons and bubbles in -ball dynamics
D. Canillas Martínez, P. Dorey, T. Romańczukiewicz +3
We show that, in the thin-wall regime, -ball--anti--ball collisions reveal chaotic behaviour. This is explained by the resonant energy transfer mechanism triggered by the int…
Quantum correlations in a gravitational collapse simulation with SpheriCo.jl
Benjamin Berczi, Magdalena Eriksson, Thanasis Giannakopoulos +1
We report on work using a newly developed code, SpheriCo.jl, that computes the gravitational collapse of a spherical scalar field, where the scalar can be either a classical field,…
Perturbative gravitational wave predictions for the real-scalar extended Standard Model
Oliver Gould, Paul Saffin
We perform a state-of-the-art study of the cosmological phase transitions of the real-scalar extended Standard Model. We carry out a broad scan of the parameter space of this model…
