Reference Frames and Gravitational-Wave Polarizations: Symmetry Classification and Preferred-Frame Phenomenology
Jie Zhu, Hao Li
Gravitational wave (GW) polarizations are traditionally classified in a fixed frame ( classification), which does not account for how polarization patterns change under Loren…
Revisit Static Aether: Exact Vacuum Solution in Einstein-Aether Theory and Its Analytic Extension
Jie Zhu, Hao Li
We obtain an exact analytical vacuum solution of Einstein-Aether theory with a strictly static aether configuration and investigate its maximal extension. The solution depends only…
Dynamic Aspects of Bumblebee Gravity: Post-Newtonian Approach
Jie Zhu, Hao Li
In this work, we investigate the dynamic aspects of Bumblebee gravity via the parameterized post-Newtonian method. We find that the PPN framework is self-consistent up to 1.5PN ord…
New Exact Vacuum Solutions in Extended Bumblebee Gravity
Jie Zhu, Hao Li
We investigate the static spherically symmetric vacuum solutions in a generalized bumblebee gravity model characterized by non-minimal couplings and . We demo…
Testing the strong equivalence principle with multimessenger binary neutron star mergers
Jie Zhu, Hanlin Song, Zhenwei Lyu +5
The constancy of the gravitational constant is a cornerstone of the strong equivalence principle and of general relativity, yet its possible temporal variation remains a key ta…
Exploring Lorentz Violation in Spacetime through Universal Finsler Geometry
Jie Zhu, Hao Li, Bo-Qiang Ma
Finsler geometry serves as a fundamental and natural extension of Riemannian geometry, providing a valuable framework for investigating Lorentz violation in spacetime. Previous stu…
Parameterized Post-Newtonian Analysis of Quadratic Gravity and Solar System Constraints
Jie Zhu, Hao Li
This work systematically investigates the post-Newtonian behavior of general quadratic gravity in the weak-field regime. By extending the Einstein-Hilbert action to include quadrat…

Jie Zhu, Hao Li
The static spherical vacuum solution in a bumblebee gravity model where the bumblebee field has a two-component space-like, light-like, and time-like vacuum expectation value…
Gravitational-wave constraints on noncommutative spacetime from GW190814
Hanlin Song, Hao Li, Zhenwei Lyu +3
Recent advances in noncommutative geometry and string theory have stimulated increasing research on noncommutative gravity. The detection of gravitational waves~(GW) opens a new wi…
Static Spherical Vacuum Solution to Bumblebee Gravity with Time-like VEVs
Hao Li, Jie Zhu
The static spherical vacuum solution in a bumblebee gravity model where the bumblebee field \(B_μ\) has a one-component time-like vacuum expectation value \(b_μ\) is studied. We sh…
