Magnetic Helicity, Magnetic Monopoles, and Higgs Winding
Hajime Fukuda, Yuta Hamada, Kohei Kamada +2
Changes in magnetic helicity are often discussed across a variety of fields, from condensed matter physics to early universe cosmology. It is frequently stated that the helicity ch…

Revisiting constraints on magnetogenesis from baryon asymmetry
Yuta Hamada, Kyohei Mukaida, Fumio Uchida
Magnetic fields in the universe potentially serve as a messenger of primordial physics. The observationally suggested intergalactic magnetic fields may be a relic of helical primor…

Symmetries of Hot SM, Magnetic Flux & Baryogenesis from Helicity Decay
Yuta Hamada, Kyohei Mukaida, Fumio Uchida
We revisit the electroweak crossover of the Standard Model (SM) in the early Universe, focusing on the interplay between generalized global symmetries, magnetic flux dynamics, and…
