Effective metric for binaries in framework of EOB theory to fifth PM order
Jiliang Jing, Weike Deng, Sheng Long
To establish a self-consistent effective one-body (EOB) theory that describes the dynamical evolution of binary systems based on the post-Minkowskian (PM) approximation, where the…
Quasinormal modes and echoes of a double braneworld
Qin Tan, Sheng Long, Weike Deng +1
In this work, we study the gravitational quasinormal modes and the gravitational echoes of a double braneworld. The double braneworld is a kind of split thick brane, which is cruci…
Motion of spinning particles around black hole in a dark matter halo
Qin Tan, Weike Deng, Sheng Long +1
The motion of a rapidly rotating object in curved spacetime is affected by the spin-curvature force, an effect captured in the motion of spinning test particles. Recently, Cardoso…
Graviscalar quasinormal modes and asymptotic tails of a thick brane
Qin Tan, Sheng Long, Weike Deng +1
In this work, we investigate the graviscalar quasinormal modes (QNMs) and their asymptotic tail behavior of a thick brane. Considering the scalar perturbations of the thick brane m…
Effective one-body theory of spinless binary evolution dynamics
Jiliang Jing, Sheng Long, Weike Deng +1
The effective one-body (EOB) theory provides an innovative framework for analyzing the dynamics of binary systems, as articulated by Hamilton's equations. This paper investigates a…
Scalar-gravitational quasinormal modes and echoes in a five dimensional thick brane
Weike Deng, Sheng Long, Qin Tan +2
The scalar perturbations of thick braneworld models provide critical insights into their matter-geometry relationship, distinct from tensor modes. This work systematically investig…
