Dynamical Casimir Effect and Vacuum Friction in the Near-Horizon Geometry of a Black Hole

Hamed Hadi, Amin Rezaei Akbarieh, Goksel Daylan Esmer

We investigate the Dynamical Casimir Effect (DCE) for a relativistic scalar field confined within a cavity possessing moving boundaries in the (1+1)-dimensional near-horizon geomet…

Ergosphere Geometry and Thermodynamic Properties of Boosted Kerr-Taub-NUT Solutions in Kaluza-Klein Theory

Hasan Oguz, Goksel Daylan Esmer

We investigate rotating black holes obtained by applying a Kaluza-Klein boost to the Kerr-Taub-NUT spacetime and study the resulting four-dimensional geometry and thermodynamics af…

Hidden Symmetries and Gyromagnetic Ratio of Kerr-Newman Black Holes in Gravity

Göksel Daylan Esmer, Saliha Türkmen

We explore hidden symmetries in electrically charged, four-dimensional rotating Kerr-Newman black hole within gravity. By deriving the Killing and Killing-Yano tensors, we e…

Light double-gluon hybrid states

G. Daylan Esmer, B. Barsbay, K. Azizi +2

We investigate light hybrid mesons composed of a light quark-antiquark pair and two gluons within the framework of QCD sum rules. We focus on states with quantum numbers $J^{\mathr…

Kerr-Newman-de Sitter black holes in gravity with constant curvature: horizon structure and extremality

Alikram N. Aliev, Göksel Daylan Esmer

The theory of gravity with constant curvature (i.e. constant scalar curvature) admits rotating and charged black hole solutions obtained from the Kerr-Newman-(A)dS metrics o…

Decays of the light hybrid meson

G. Daylan Esmer, K. Azizi, H. Sundu +1

The full width of the light isovector hybrid meson with spin-parities and content is evaluated by con…
