Analytic Electromagnetic Effective Source for Geodesic Orbit in Schwarzschild Spacetime
Xuchen Lu, Yungui Gong, Bokai Zhang +2
Self-force effects are essential for accurately describing the motion of small bodies in curved spacetime. The effective-source approach privides a promising route to higher-order…

Frequency-domain extended-effective-source gravitational self-force for eccentric Schwarzschild orbits
Xuchen Lu, Yungui Gong, Bokai Zhang +2
Effective-source formulations provide a practical route to gravitational self-force (GSF) calculations when singular retarded fields cannot be handled directly mode by mode. Up to…

The point-particle-limit effective-source approach for computing gravitational self-force in the Lorenz gauge
Chao Zhang, Yungui Gong, Xuchen Lu +1
The traditional effective-source method is hampered by complex analytical expressions and the inherent smoothness limit, which incur high computational costs and complicate impleme…
