Quadratic and cubic spherically symmetric black holes in the modified teleparallel equivalent of general relativity: energy and thermodynamics

چکیده

In \cite{Bahamonde:2019zea}, a spherically symmetric black hole (BH) was derived from the quadratic form of $f(T)$. Here we derive associated energy, invariants curvature, and torsion this BH demonstrate that higher-order contribution renders singularity weaker compared with Schwarzschild general relativity (GR). Moreover, calculate thermodynamic quantities reveal effect higher--order on these quantities. Therefore, new cubic $f(T)=T+\epsilon\Big[\frac{1}{2}\alpha T^2+\frac{1}{3}\beta T^3\Big]$, where $\epsilon<<1$, $\alpha$, $\beta$ are constants. The is characterized by two constants $\alpha$ in addition to $\epsilon$. At $\epsilon=0$ return GR. We study physics solutions via same procedure applied for BH. torsion, $\frac{1}{2}\alpha T^3$, may afford an interesting physics.

Spherically symmetric black holes in minimally modified self-dual gravity

We discuss spherically symmetric black holes in the modified self-dual theory of gravity recently studied by Krasnov, obtained adding a Weyl-curvature dependent ‘cosmological term’ to the Plebanski lagrangian for general relativity. This type of modified gravity admits two different types of singularities: one is a true singularity for the theory where the fundamental fields of the theory, as w...

Geometric Bounds in Spherically Symmetric General Relativity

We exploit an arbitrary extrinsic time foliation of spacetime to solve the constraints in spherically symmetric general relativity. Among such foliations there is a one parameter family, linear and homogeneous in the extrinsic curvature, which permit the momentum constraint to be solved exactly. This family includes, as special cases, the extrinsic time gauges that have been exploited in the pa...

Averaging spherically symmetric spacetimes in general relativity

We discuss the averaging problem in general relativity, using the form of the macroscopic gravity equations in the case of spherical symmetry in volume preserving coordinates. In particular, we calculate the form of the correlation tensor under some reasonable assumptions on the form for the inhomogeneous gravitational field and matter distribution. On cosmological scales, the correlation tenso...
