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…
A general method for solving light-like geodesics
Ren-Qi Pan, Xi He
A universal method to solve the differential equations of light-like geodesics is developed. The validity of this method depends on a new theorem, which is introduced for light-lik…
Constraints of the equation of state of dark energy from current and future observational data by piecewise parametrizations
Qiping Su, Xi He, Rong-Gen Cai
The model-independent piecewise parametrizations (0-spline, linear-spline and cubic-spline) are used to estimate constraints of equation of state of dark energy () from cur…
Phase transitions in AdS soliton spacetime through marginally stable modes
Rong-Gen Cai, Xi He, Huai-Fan Li +1
We investigate the marginally stable modes of the scalar (vector) perturbations in the AdS soliton background coupled to electric field. In the probe limit, we find that the margin…
Signature of the black hole phase transition in quasinormal modes
Xi He, Bin Wang, Rong-Gen Cai +1
We study the perturbation of the scalar field interacting with the Maxwell field in the background of d-dimensional charged AdS black hole and AdS soliton. Different from the singl…
Quasinormal modes of black holes absorbing dark energy
Xi He, Bin Wang, Shao-Feng Wu +1
We study perturbations of black holes absorbing dark energy. Due to the accretion of dark energy, the black hole mass changes. We observe distinct perturbation behaviors for absorp…
