Gravitational wave constraints on non-birefringent dispersions of gravitational waves due to Lorentz violations with GWTC-3
Cheng Gong, Tao Zhu, Rui Niu +5
The standard model extension (SME) is an effective field theory framework that can be used to study the possible violations of Lorentz symmetry in the gravitational interaction. In…
Gravitational wave constraints on Lorentz and parity violations in gravity: high-order spatial derivative cases
Cheng Gong, Tao Zhu, Rui Niu +5
High-order spatial derivatives are of crucial importance for constructing the low energy effective action of a Lorentz or parity violating theory of quantum gravity. One example is…

Qiang Wu, Tao Zhu, Rui Niu +2
The discovery of gravitational waves (GWs) from the compact binary components by LIGO/Virgo Collaboration provides an unprecedented opportunity for testing gravity in the strong an…
Constraining scalar-tensor theories by neutron star-balck hole gravitational wave events
Rui Niu, Xing Zhang, Bo Wang +1
With the continuous upgrade of detectors, more and more gravitational wave (GW) events were captured by the LIGO Scientific Collaboration and Virgo Collaboration (LVC), which offer…
Joint Observations of Space-based Gravitational-wave Detectors: Source Localization and Implication for Parity-violating gravity
Qian Hu, Mingzheng Li, Rui Niu +1
Space-based gravitational-wave (GW) detectors, including LISA, Taiji and TianQin, are able to detect mHz GW signals produced by mergers of supermassive black hole binaries, which o…
Gravitational-Wave Implications for the Parity Symmetry of Gravity at GeV Scale
Yi-Fan Wang, Rui Niu, Tao Zhu +1
Einstein's general relativity, as the most successful theory of gravity, is one of the cornerstones of modern physics. However, the experimental tests for gravity in the high energ…
Constraining Screened Modified Gravity by Space-borne Gravitational-wave Detectors
Rui Niu, Xing Zhang, Tan Liu +3
The screened modified gravity (SMG) is a unified theoretical framework, which describes the scalar-tensor gravity with screening mechanism. Based on the gravitational-wave (GW) wav…
Constraining the scalar-tensor gravity theories with and without screening mechanisms by combined observations
Xing Zhang, Rui Niu, Wen Zhao
Screened modified gravity (SMG) and Brans-Dicke (BD) gravity are typical examples of scalar-tensor theories with and without screening mechanisms, which can suppress the scalar fie…
Constraining the non-Einsteinian polarizations of gravitational waves by pulsar timing array
Rui Niu, Wen Zhao
Pulsar timing array (PTA) provides an excellent opportunity to detect the gravitational waves (GWs) in nanoHertz frequency band. In particular, due to the larger number of "arms" i…
