Collapsing domain walls with -violating coupling to thermalized fermions and their impact on gravitational wave detections
Qing-Quan Zeng, Xi He, Zhao-Huan Yu +1
We study the dynamics of domain walls formed through the spontaneous breaking of an approximate symmetry in a scalar field, focusing on their collapse under the infl…

Axion Emission from Proton Cooper Pairs in Neutron Stars
Koichi Hamaguchi, Natsumi Nagata, Jiaming Zheng
We investigate axion emission from singlet proton Cooper pairs in neutron stars, a process that dominates axion emission in young neutron stars in the KSVZ model. By re-deriving it…
