Gravitational Wave Detection Based on Gravitomagnetic Effects
Yu-Qi Dong, Zhoujian Cao, Yu-Xiao Liu
In this paper, we explore the feasibility of detecting gravitomagnetic effects generated by gravitational waves, by monitoring the relative orientation of the angular momentum vect…
Complete quasinormal modes of Type-D black holes
Changkai Chen, Jiliang Jing, Zhoujian Cao +1
Quasinormal mode (QNM) spectra of black holes exhibit two open problems [Conf. Proc. C 0405132, 145 (2004); CQG 26, 163001 (2009)]: (i) the discontinuity in highly damped QNMs betw…
Covariant dynamics from static spherically symmetric geometries
Cong Zhang, Zhoujian Cao
This work reveals a fundamental link between general covariance and Birkhoff's theorem. We extend Birkhoff's theorem from general relativity to a broad class of generally covariant…
Impact of particle production during inflation on the CMB detection
Xunliang Yang, Zhe Yu, Zhoujian Cao
This work focuses on particle production described by a nonminimally coupled model during inflation. In this model, three parameters determine the characteristic frequency and stre…
