Curvature as a control field in helicoidal two-body systems
Abdullah Guvendi, Hassan Hassanabadi
Geometry is increasingly recognized as an active physical resource capable of modifying the behavior of dynamical systems beyond conventional external control mechanisms. Here, we…
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…
Spectroscopic structure of Non-Hermitian -Symmetric Klein--Gordon Fields in a Magnetized Cosmic String Spacetime
Omar Mustafa, Abdullah Guvendi
We investigate non-Hermitian -symmetric Klein--Gordon (KG) fields in a magnetized cosmic string spacetime. A complex non-minimal scalar interaction, $\mathcal{F}_μ=(…
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…
Non-Hermitian symmetric Klein-Gordon fields in Lorentz-violating wormholes spacetime background
Omar Mustafa, Abdullah Guvendi
We investigate a -symmetric Klein--Gordon (KG) oscillator in a -dimensional Lorentz-violating (LV) traversable wormhole spacetime. The geometry is characterize…
