First-order electroweak phase transitions: A nonperturbative update (2022)
Journal Article
Gould, O., Güyer, S., & Rummukainen, K. (2022). First-order electroweak phase transitions: A nonperturbative update. Physical Review D, 106(11), Article 114507. https://doi.org/10.1103/physrevd.106.114507

We study first-order electroweak phase transitions nonperturbatively, assuming any particles beyond the Standard Model are sufficiently heavy to be integrated out at the phase transition. Utilizing high temperature dimensional reduction, we perform l... Read More about First-order electroweak phase transitions: A nonperturbative update.

Radiative first-order phase transitions to next-to-next-to-leading order (2022)
Journal Article
Ekstedt, A., Gould, O., & Löfgren, J. (2022). Radiative first-order phase transitions to next-to-next-to-leading order. Physical Review D, 106(3), Article 036012. https://doi.org/10.1103/PhysRevD.106.036012

We develop new perturbative tools to accurately study radiatively induced first-order phase transitions. Previous perturbative methods have suffered internal inconsistencies and been unsuccessful in reproducing lattice data, which is often attributed...

Search for magnetic monopoles produced via the Schwinger mechanism (2022)
Journal Article
Acharya, B., Alexandre, J., Benes, P., Bergmann, B., Bertolucci, S., Bevan, A., …Vives, O. (2022). Search for magnetic monopoles produced via the Schwinger mechanism. Nature, 602(7895), 63-67. https://doi.org/10.1038/s41586-021-04298-1

Electrically charged particles can be created by the decay of strong enough electric fields, a phenomenon known as the Schwinger mechanism1. By electromagnetic duality, a sufficiently strong magnetic field would similarly produce magnetic monopoles,... Read More about Search for magnetic monopoles produced via the Schwinger mechanism.
