Magnetic localization and spectral asymmetry of a charged particle at a screw dislocation
Claudio Furtado, Omar Mustafa, Hassan Hassanabadi +1
We study a charged particle moving outside a spiral (screw) dislocation in a uniform magnetic field. Although the geometry is locally Euclidean, its global screw identification cou…
Charged Klein-Gordon modes on an Ellis wormhole: magnetic confinement and conditional Heun solvability
Abdullah Guvendi, Omar Mustafa
We study charged Klein-Gordon modes on a -dimensional Ellis traversable wormhole in an external magnetic field defined as uniform in an auxiliary Euclidean embedding space.…
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…
Phase-space structure and nonlinear dynamics of a charged particle on a helicoidal manifold under a magnetic field
Abdullah Guvendi, Hassan Hassanabadi, Semra Gurtas Dogan +1
We analyze the classical dynamics of a charged particle constrained to a helicoidally embedded Riemannian manifold in under a uniform magnetic field in the ambient s…
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…
Lorentz-Violating Wormhole Optics
Omar Mustafa, Semra Gurtas Dogan, Abdulkerim Karabulut +1
We study massless spin-1 field propagation in a static, circularly symmetric -dimensional wormhole with spatial Lorentz-violating anisotropy characterized by the throat radi…
Wave Propagation and Effective Refraction in Lorentz-Violating Wormhole Geometries
Semra Gurtas Dogan, Omar Mustafa, Abdulkerim Karabulut +1
We study the propagation of massless scalar waves in static, spherically symmetric Lorentz-violating wormhole spacetimes within a geometric-optical framework. Starting from a gener…
