Explore a High Energy Physics seminar where Junwu Huang from Perimeter Institute discusses two non-thermal classical mechanisms for string formation in the early and late universe, drawing parallels to vortex formations in superconductors and superfluids. Learn about the "string bosenova" phenomenon where gauged strings form inside vector superradiance clouds around spinning black holes, and discover how periodic string formation in systems with global U(1) symmetry can create distinctive gravitational wave signatures appearing as a forest of peaks in the spectrum. The presentation also touches on implications for dark photon and axion dark matter production, as well as potential connections to baryogenesis, offering insights into how these novel string production mechanisms could be detected by gravitational wave observatories.
