Dynamical backreaction of a mass-acquiring scalar field on first-order phase transitions
Yuan-Jie Li, Jing Liu, Zong-Kuan Guo
Phase transitions in the early Universe give rise to effective masses for massless fields in the symmetry-broken phase. We perform lattice simulations to study the dynamical impact…

Ring formation from black hole superradiance through repeated particle production on bound orbits
Zhen-Hong Lyu, Rong-Gen Cai, Zong-Kuan Guo +2
Ultralight bosonic fields around a rotating black hole can extract energy and angular momentum through the superradiant instability and form a dense cloud. We investigate the scena…

Dynamics of domain walls with bias directions
Yuan-Jie Li, Jing Liu, Zong-Kuan Guo
The spontaneous breaking of a discrete symmetry can lead to the formation of domain walls in the early Universe. In this work, we explore the impact of bias directions on the dynam…
