Thermal Schwinger pair production at arbitrary coupling
We calculate the rate of thermal Schwinger pair production at arbitrary coupling in weak external fields. Our calculations are valid independently of many properties of the charged particlesExpand
Theoretical uncertainties for cosmological first-order phase transitions
We critically examine the magnitude of theoretical uncertainties in perturbative calculations of first-order phase transitions, using the Standard Model effective field theory as our guide. In theExpand
Magnetic Monopole Mass Bounds from Heavy-Ion Collisions and Neutron Stars.
Magnetic monopoles, if they exist, would be produced amply in strong magnetic fields and high temperatures via the thermal Schwinger process. Such circumstances arise in heavy-ion collisions and inExpand
Observing Thermal Schwinger Pair Production
We study the possibility of observing Schwinger pair production enhanced by a thermal bath of photons. We consider the full range of temperatures and electric field intensities, and identify the mostExpand
Towards Schwinger production of magnetic monopoles in heavy-ion collisions
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 such collisions andExpand
Nonperturbative analysis of the gravitational waves from a first-order electroweak phase transition
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 framework of dimensionallyExpand
Worldline sphaleron for thermal Schwinger pair production
With increasing temperatures, Schwinger pair production changes from a quantum tunneling to a classical, thermal process, determined by a worldline sphaleron. We show this and calculate theExpand
Schwinger pair production of magnetic monopoles: momentum distribution for heavy-ion collisions
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 heavy-ion collisions.Expand
On the perturbative expansion at high temperature and implications for cosmological phase transitions
We revisit the perturbative expansion at high temperature and investigate its convergence by inspecting the renormalisation scale dependence of the effective potential. Although at zero temperatureExpand
Real scalar phase transitions: a nonperturbative analysis
We study the thermal phase transitions of a generic real scalar field, without a Z2-symmetry, referred to variously as an inert, sterile or singlet scalar, or ϕ3 + ϕ4 theory. Such a scalar fieldExpand
