New results on the dynamics of critical collapse
Jun-Qi Guo, Yu Hu, Pan-Pan Wang +1
We study the dynamics of the critical collapse of a spherically symmetric scalar field. Approximate analytic expressions for the metric functions and matter field in the large-radi…
Para-differential Calculus on Compact Lie Groups and Spherical Capillary Water Waves
Chengyang Shao
This paper provides a para-differential calculus toolbox on compact Lie groups and homogeneous spaces. It helps to understand non-local, nonlinear partial differential operators wi…
Onset of chaotic gravitational lensing in non-Kerr rotating black holes with quadrupole mass moment
Wen-Hao Wu, Cheng-Yong Zhang, Cheng-Gang Shao +1
In the electromagnetic channel, chaotic gravitational lensing is a peculiar phenomenon in strong gravitational lensing. In this work, we analyze the properties and emergence of cha…
Longtime Dynamics of Irrotational Spherical Water Drops: Initial Notes
Chengyang Shao
In this note, we propose several unsolved problems concerning the irrotational oscillation of a water droplet under zero gravity. We will derive the governing equation of this phys…
On second-order combinatorial algebraic time-delay interferometry
Wei-Liang Qian, Pan-Pan Wang, Zhang-Qi Wu +3
Inspired by the combinatorial algebraic approach proposed by Dhurandhar {\it et al.}, we propose two novel classes of second-generation time-delay interferometry (TDI) solutions an…
Matrix method for perturbed black hole metric with discontinuity
Shui-Fa Shen, Wei-Liang Qian, Kai Lin +2
Recent studies based on the notion of black hole pseudospectrum indicated substantial instability of the fundamental and high-overtone quasinormal modes. Besides its theoretical no…
