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…
Thermodynamic Geometry, Heat Engines, and Topology of Sharma--Mittal ModMax-dRGT Black Holes
Hassan Hassanabadi, Abdullah Guvendi, Dhruba Jyoti Gogoi +2
We investigate the thermodynamic structure of charged AdS black holes in ModMax nonlinear electrodynamics coupled to dRGT-like massive gravity, incorporating Sharma--Mittal entropy…
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…
Null geodesics and shadows of slowly rotating wormholes immersed in dark matter halos
Abdelghani Errehymy, Abdullah Guvendi, Semra Gurtas Dogan +1
We study slowly rotating traversable wormholes embedded in realistic galactic dark matter halos, including Navarro-Frenk-White (NFW), Bose-Einstein Condensate (Thomas-Fermi, TF), a…
