Rotating Black Hole in Extended Chern-Simons Modified Gravity

How do black holes spin in Chern-Simons modified gravity?

No Kerr-like exact solution has yet been found in Chern-Simons modified gravity. Intrigued by this absence, we study stationary and axisymmetric metrics that could represent the exterior field of spinning black holes. For the standard choice of the background scalar, the modified field equations decouple into the Einstein equations and additional constraints. These constraints eliminate essenti...

Black Hole entropy in D = 2 + 1 dimensions from extended Chern - Simons term in a gravitational

We study the contribution to entropy of Black Holes in D = 2+1 dimensions from an extension of the Chern Simons theory including higher derivative in a curved space-time [2]. [email protected]/[email protected] [email protected]

Black Hole Entropy in the presence of Chern-Simons Terms

We derive a formula for the black hole entropy in theories with gravitational Chern-Simons terms, by generalizing Wald’s argument which uses the Noether charge. It correctly reproduces the entropy of three-dimensional black holes in the presence of Chern-Simons term, which was previously obtained via indirect methods.

Flat rotation curves in Chern-Simons modified gravity

Black hole entropy and SU(2) Chern-Simons theory.

Black holes (BH's) in equilibrium can be defined locally in terms of the so-called isolated horizon boundary condition given on a null surface representing the event horizon. We show that this boundary condition can be treated in a manifestly SU(2) invariant manner. Upon quantization, state counting is expressed in terms of the dimension of Chern-Simons Hilbert spaces on a sphere with punctures...
