报告摘要：Symmetry is a central topic in modern fundamental physics, both in quantum physics and relativity. For gravitational interaction, the Lorentz and parity symmetries are two fundamental symmetries in general relativity. However, the violation of both the Lorentz and parity symmetries can arise from a lot of quantum theories of gravity, including string theory, loop quantum gravity, and Horava-Lifshitz gravity. Thus, it is important to test the symmetries of gravity in experiments and observations. In this talk, I will focus on the violation of the parity symmetry in gravity. I will briefly review several parity-violating gravities and their possible implications in solar system experiments, binary pulsars, and other astrophysical observations. In addition, I will also discuss our recent works on testing the parity violation in gravity by using GWs.
