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…
Charged particle dynamics in singular spacetimes: hydrogenic mapping and curvature-corrected thermodynamics
Abdullah Guvendi, Semra Gurtas Dogan, Omar Mustafa +1
We analyze the dynamics of charged test particles in a singular, horizonless spacetime arising as the massless limit of a charged wormhole in the Einstein--Maxwell--Scalar (EMS) fr…
Twist-Induced Effects on Weyl Pairs in Magnetized Graphene Nanoribbons
Semra Gurtas Dogan, Kobra Hasanirokh, Omar Mustafa +1
This paper presents an analytical investigation into the dynamics of Weyl pairs within magnetized helicoidal graphene nanoribbons. By embedding a curved surface into flat Minkowski…
Vector bosons in the rotating frame of negative curvature wormholes
Abdullah Guvendi, Semra Gurtas Dogan
In this study, we investigate the relativistic dynamics of vector bosons within the context of rotating frames of negative curvature wormholes. We seek exact solutions for the full…
Coupled fermion-antifermion pairs within a traversable wormhole
Abdullah Guvendi, Semra Gurtas Dogan, Omar Mustafa
This study investigates the dynamics of fermion-antifermion pairs within a traversable wormhole spacetime by solving the two-body covariant Dirac equation with a position-dependent…
Photonic Modes in Twisted Graphene Nanoribbons
A. Guvendi, S. G. Dogan, O. Mustafa +1
This study investigates the behavior of photonic modes in twisted graphene nanoribbons (TGNRs) using an analytical approach based on solving the fully covariant vector boson equati…
