Multi-Instantons, Multi-Axions, and Non-Invertible Symmetries in 4d QFT
Sungwoo Hong, Hyungyu Kim, Sung Mook Lee +1
We study non-invertible global symmetries in 4d quantum field theories, aiming to generalize existing discussions to theories with multiple instantons and axions, and to make the s…

Gravitational Wave with Domain Wall Dominance
Sungwoo Hong, Sung Mook Lee, Qiuyue Liang
Domain walls (DWs) can be produced when a discrete symmetry is spontaneously broken, and long-lived DWs can dominate the energy density of the universe. In this work, we explore th…
