Quantum Effects of Low-frequency Gravitational Wave Sources

报告题目:Quantum Effects of Low-frequency Gravitational Wave Sources

报告人:王静 教授(广西师范大学)




   Since the detection of GW events by LIGO, the issues on gravitational waves (GWs) have become hot topics. The typical GW sources, black hole and neutron star (NS) binaries, also get into our scope once more. One class of the GW sources, NS binaries, provide extreme physical conditions and manifest exotic phenomena, such as high temperature, immense density, fast spin, strong magnetic fields, and strong gravity, which make them to be the typical compact systems involving four fundamental interactions. In this talk, I would like to discuss our work about quantum effects of the low-frequency GW sources, inspiraling NS binaries with separation of 109 m. I will firstly introduce the canonical quantization into the gravitational dynamics of such systems, which gives rise to the gravitational Higgs mechanism. Secondly, I ‘d like to talk about the application of covariant quantization to the systems and the corresponding gravitational Casimir effects. Finally, I will discuss the relations between these quantum effects and GW properties, as well as the possible detection.
