Finite-Field QED Corrections to Vacuum Birefringence and Magnetar Polarization Transport
S. Abbassi, F. A. Chishtie, S. R. Valluri
We study low-energy photon propagation in a constant magnetic field within the finite-field one-loop Heisenberg--Euler framework and apply the resulting mode-dependent refractive i…

The Role of r-Modes in Pulsar Spin-down, Pulsar Timing, and Gravitational Waves
Xiyuan Li, Shahram Abbassi, Varenya Upadhyaya +2
We investigate the role of r-mode oscillations in pulsar spin-down and their implications for gravitational wave emission and pulsar timing analysis. Using a non-linear differentia…
