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.…
Theoretical uncertainties for cosmological first-order phase transitions
Djuna Croon, Oliver Gould, Philipp Schicho +2
We critically examine the magnitude of theoretical uncertainties in perturbative calculations of first-order phase transitions, using the Standard Model effective field theory as o…
Nonperturbative analysis of the gravitational waves from a first-order electroweak phase transition
Oliver Gould, Jonathan Kozaczuk, Lauri Niemi +3
We present the first end-to-end nonperturbative analysis of the gravitational wave power spectrum from a thermal first-order electroweak phase transition (EWPT), using the framewor…
Towards Schwinger production of magnetic monopoles in heavy-ion collisions
Oliver Gould, David L. -J. Ho, Arttu Rajantie
Magnetic monopoles may be produced by the Schwinger effect in the strong magnetic fields of peripheral heavy-ion collisions. We review the form of the electromagnetic fields in suc…
