Effective field theory approach to thermal bubble nucleation
Oliver Gould, Joonas Hirvonen
The standard vacuum bounce formalism suffers from inconsistencies when applied to thermal bubble nucleation, for which ad hoc workarounds are commonly adopted. Identifying the leng…
Vacuum bubble collisions: from microphysics to gravitational waves
Oliver Gould, Satumaaria Sukuvaara, David Weir
We comprehensively study the effects of bubble wall thickness and speed on the gravitational wave emission spectrum of collisions of two vacuum bubbles. We numerically simulate a l…
First experimental search for production of magnetic monopoles via the Schwinger mechanism
B. Acharya, J. Alexandre, P. Benes +64
Schwinger showed that electrically-charged particles can be produced in a strong electric field by quantum tunnelling through the Coulomb barrier. By electromagnetic duality, if ma…
On the perturbative expansion at high temperature and implications for cosmological phase transitions
Oliver Gould, Tuomas V. I. Tenkanen
We revisit the perturbative expansion at high temperature and investigate its convergence by inspecting the renormalisation scale dependence of the effective potential. Although at…
Schwinger pair production of magnetic monopoles: momentum distribution for heavy-ion collisions
Oliver Gould, David L. -J. Ho, Arttu Rajantie
Magnetic monopoles may be produced by the dual Schwinger effect in strong magnetic fields. Today, the strongest known magnetic fields in the universe are produced fleetingly in hea…
Real scalar phase transitions: a nonperturbative analysis
Oliver Gould
We study the thermal phase transitions of a generic real scalar field, without a -symmetry, referred to variously as an inert, sterile or singlet scalar, or theory.…
