Quasinormal modes of scalar and Maxwell field perturbations coupled to the Einstein tensor in generalized Nariai spacetimes
Xin Qin, Xiongying Qiao, Qiyuan Pan +3
We investigate the quasinormal modes of scalar and Maxwell field perturbations coupled to the Einstein tensor in generalized Nariai spacetimes. Our results show that, for both type…
Thin accretion disk around a Kerr black hole immersed in swirling universes
Yuxin Ouyang, Xuan Zhou, Songbai Chen +1
We have studied the properties of thin accretion disks around swirling-Kerr black holes, which own an extra swirling parameter describing the rotation of the immersed universe. Our…
Geometrically thick equilibrium tori around a dyonic black hole with quasi-topological electromagnetism
Xuan Zhou, Songbai Chen, Jiliang Jing
We study geometrically thick and non-self gravitating equilibrium tori orbiting a static spherically symmetric dyonic black hole with quasi-topological electromagnetism. Our result…
Soliton resolution and asymptotic stability of -solitons to the Degasperis-Procesi equation on the line
Xuan Zhou, Zhaoyu Wang, Engui Fan
The Degasperis-Procesi (DP) equation \begin{align} &u_t-u_{txx}+3κu_x+4uu_x=3u_x u_{xx}+uu_{xxx}, \nonumber \end{align} serving as a model delineating the propagation of shallow wa…
Long time asymptotic behavior for the nonlocal mKdV equation in space-time solitonic regions-II
Xuan Zhou, Engui Fan
We study the long time asymptotic behavior for the Cauchy problem of an integrable real nonlocal mKdV equation with nonzero initial data in the solitonic regions \begin{align*} &q_…
Long time asymptotics for the nonlocal mKdV equation with finite density initial data
Xuan Zhou, Engui Fan
In this paper, we consider the Cauchy problem for an integrable real nonlocal (also called reverse-space-time) mKdV equation with nonzero boundary conditions \begin{align*} &q_t(x,…
Effect of noncircularity on the dynamic behaviors of particles in a disformal rotating black-hole spacetime
Xuan Zhou, Songbai Chen, Jiliang Jing
A disformal rotating black-hole solution is a black-hole solution in quadratic degenerate higher-order scalar-tensor theories. It breaks the circular condition of spacetime differe…
Chaotic motion of scalar particle coupling to Chern-Simons invariant in Kerr black hole spacetime
Xuan Zhou, Songbai Chen, Jiliang Jing
We present firstly the equation of motion for the test scalar particle coupling to the Chern-Simons invariant in Kerr black hole spacetime by the short-wave approximation. We have…
