Constraints on charged Symmergent black hole from shadow and lensing

Beyhan Puliçe, Reggie C. Pantig, Ali Övgün +1

In this paper, we report on exact charged black hole solutions in symmergent gravity with Maxwell field. Symmergent gravity induces the gravitational constant , quadratic curvat…

Thin accretion disk images of the black hole in symmergent gravity

İlim İrfan Çimdiker, Ali Övgün, Durmuş Demir

In this paper, we study circular orbits, effective potential, and thin-accretion disk of a black hole in symmergent gravity within the Novikov-Thorne model in a way including the e…

Gauge and Poincare properties of the UV cutoff and UV completion in quantum field theory

Durmus Demir

The ultraviolet (UV) cutoff on a quantum field theory (QFT) can explicitly break or conserve the Poincare (translation) symmetry. And the very same cutoff can explicitly break or c…

Quasinormal modes and greybody factors of symmergent black hole

Dhruba Jyoti Gogoi, Ali Övgün, Durmuş Demir

Symmergent gravity is an emergent gravity framework in which gravity emerges guided by gauge invariance, accompanied by new particles, and reconciled with quantum fields. In this p…

Probing Geometric Proca in Metric-Palatini Gravity with Black Hole Shadow and Photon Motion

Elham Ghorani, Beyhan Puliçe, Farruh Atamurotov +3

Extended metric-Palatini gravity, quadratic in the antisymmetric part of the affine curvature, is known to lead to the general relativity plus a geometric Proca field. The geometri…

Dimensional Regularization in Quantum Field Theory with Ultraviolet Cutoff

Durmus Demir, Canan Karahan, Ozan Sargın

In view of various field-theoretic reasons, in the present work, we study the question of if the usual dimensional regularization can be extended to quantum field theories with an…
