Spin precession in general stationary and axisymmetric spacetimes
Shaofei Xu, Junji Jia
This paper investigates the spin precession of test particles moving in the equatorial plane of general stationary and axisymmetric spacetimes using the Mathisson-Papapetrou-Dixon…

Periapsis shift in magnetized stationary and axisymmetric spacetimes
Yuhan Zhou, Junji Jia
In this work, we conduct a detailed study of the precession of charged particles in stationary and asymmetric spacetimes with external magnetic fields. Specifically, we develop the…

From Matter Density to Deflection Angle and Gravitational Lensing Using a Perturbative Method
Peiran Liu, Xiaotian Zhang, Junji Jia
In this work, we develop a perturbative method to compute the deflection angle of null or timelike signals in spacetimes filled with a static and spherically symmetric (SSS) perfec…
