Fluid-membrane Descriptions of Various Black Holes
Cagdas Ulus Agca, Bayram Tekin
The membrane paradigm of black holes is an effective theory that replaces the event horizon with a fictitious yet tangible fluid. It has provided us with valuable insights, especia…
Vanishing of Conserved Charges in Cotton Gravity
Emel Altas, Bayram Tekin
Cotton gravity was recently introduced as a higher derivative extension of General Relativity. The field equations of the theory involve the rank-3 Cotton tensor. Here we show that…
Some Lower Dimensional Quantum Field Theories Reduced from Chern-Simons Gauge Theories
Burak Oğuz, Bayram Tekin
We study symmetry reductions in the context of Euclidean Chern-Simons gauge theories to obtain lower dimensional field theories. Symmetry reduction in certain gauge theories is a c…
Refined Thermodynamics of Black Holes with Proper Conserved Charges
Aydin Tavlayan, Bayram Tekin
Field equations of a classical, geometric, theory of gravity, augmented with some semiclassical considerations strongly suggest that the gravitational field representing a stationa…
Membrane Paradigm Approach to the Johannsen-Psaltis Black Hole
Cagdas Ulus Agca, Bayram Tekin
The Johannsen-Psaltis (JP) black hole is a phenomenologically viable metric obtained by judiciously deforming the Kerr black hole such that the metric is asymptotically flat and ca…
Constraints and Time Evolution in Generic (Riemann) Gravity
Emel Altas, Bayram Tekin
We give a detailed canonical analysis of the -dimensional (Riemann) gravity, correcting the earlier results in the literature. We also write the field equations in the Fische…
