Optical and Thermodynamic Signatures of Lorentz Symmetry Breaking in Bumblebee AdS Black Holes
Behzad Eslam Panah, Abdullah Guvendi, Semra Gurtas Dogan +1
We investigate the impact of spontaneous Lorentz symmetry breaking on scalar wave propagation, null geodesics, and thermodynamic behavior of four-dimensional asymptotically AdS bla…

Electromagnetic wave propagation in static black hole spacetimes: an effective refractive index description in Schwarzschild geometry
Abdullah Guvendi, Omar Mustafa Semra Gurtas Dogan, Hassan Hassanabadi
We investigate electromagnetic wave propagation in static, spherically symmetric black hole spacetimes using a covariant and gauge-invariant framework based on the established Maxw…
