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…

Damped photonic modes in helical graphene
Abdullah Guvendi, Omar Mustafa, Abdulkerim Karabulut
We analyze the behavior of spin-1 vector bosons in helical spacetime, focusing on photonic modes in helical graphene structures. We model the helical graphene surface as a smooth,…
