White dwarf-neutron star matter transition and the effect of light elements
Yao Ma, Yong-Liang Ma, Ruo-Xi Wu +1
White dwarfs and neutron stars are unique laboratories for dense nuclear matter physics. We develop a single relativistic mean-field framework that treats both classes of compact s…
Solving Hamiltonian Constraint Equation with Physics-Informed Neural Networks
Yu-Chen Zhou, Hao Ma, Zhoujian Cao +6
Numerical relativity (NR), solving Einstein equation numerically, plays an important role in source modelling for gravitational wave astronomy. Traditional methods for NR including…
Analytical Modeling of Far-Field Wavefront Error with Beam-Waist and Lateral-Shift Effects in Spaceborne Laser Interferometry
Ya-Zheng Tao, Rui-Hong Gao, Guangzhou Xu +1
The coupling between far-field wavefront error (WFE) and laser pointing jitter is an important source of tilt-to-length (TTL) noise in spaceborne laser interferometric links. We ex…
White Dwarf Structure and Binary Inspiral Gravitational Waves from Quantum Hadrodynamics
Ling-Jun Guo, Yao Ma, Yong-Liang Ma +2
White dwarfs, one of the compact objects in the universe, play a crucial role in astrophysical research and provide a platform for exploring nuclear physics. In this work, we exten…
Intermediate-mass-ratio inspirals with general dynamical friction in dark matter minispikes
Yu-Chen Zhou, Hong-Bo Jin, Cong-Feng Qiao +1
The intermediate-mass-ratio inspirals (IMRIs) may be surrounded by dark matter (DM) minispikes. The dynamical friction from these DM minispike structures can affect the dynamics an…
Beam quality factor, spot rotation angle, and angular speed in general laser beams
Zhen-Xiang Hao, Ruo-Xi Wu, Hong-Bo Jin +2
A unified definition for the rotation angle and rotation angular speed of general beams, including those with orbital angular momentum (OAM), has been lacking until now. The rotati…
