More is Different: Multi-Axion Dynamics Changes Topological Defect Evolution
Junseok Lee, Kai Murai, Fuminobu Takahashi +1
We study topological defects in multi-axion models arising from multiple Peccei-Quinn (PQ) scalars. Using a simplified two-axion system, we reveal fundamental differences in the ev…
Induced Domain Walls of QCD Axion, and Gravitational Waves
Junseok Lee, Kai Murai, Fuminobu Takahashi +1
We show that heavy axion domain walls induce domain walls of the QCD axion through a mixing between the heavy axion and the QCD axion, even when the pre-inflationary initial condit…
Bubble Misalignment Mechanism for Axions
Junseok Lee, Kai Murai, Fuminobu Takahashi +1
We study the dynamics of axions at first-order phase transitions in non-Abelian gauge theories. When the duration of the phase transition is short compared to the timescale of the…
