Journal Article

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 and calculate from first principles the cross section for...

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 the corresponding rate of pair production for both spinor and sc... Read More about Worldline sphaleron for thermal Schwinger pair production.

Magnetic monopole creation (2018)
Thesis

Elementary magnetic monopoles have never been experimentally observed but there are credible theoretical reasons to believe that they may nonetheless exist. This thesis gives partial answers to the questions: if magnetic monopoles do exist, can we cr... Read More about Magnetic monopole creation.

Magnetic monopole mass bounds from heavy ion collisions and neutron stars (2017)
Journal Article

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 in neutron stars, both of which imply lower bounds on t...

Thermal Schwinger pair production at arbitrary coupling (2017)
Journal Article

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 particles produced, in particular their spin and whether they are ele...
