Reissner–Nordström Anti-de Sitter Black Holes in Mimetic F(R) Gravity
Universe, 2016 In this paper, we study under which conditions the Reissner–Nordström anti-de Sitter black hole can be a solution of the vacuum mimetic F ( R ) gravity with Lagrange multiplier and mimetic scalar potential.

Exact rotating black hole solutions for f(R) gravity by modified Newman Janis algorithm
European Physical Journal C: Particles and Fields, 2023 We show that the f(R)-gravity theories with constant Ricci scalar in the Jordan/Einstein frame can be described by Einstein or Einstein–Maxwell gravity with a cosmological term and a modified gravitational constant.

Rastall gravity is equivalent to Einstein gravity
Physics Letters B, 2018 Rastall gravity, originally developed in 1972, is currently undergoing a significant surge in popularity. Rastall gravity purports to be a modified theory of gravity, with a non-conserved stress–energy tensor, and an unusual non-minimal coupling between ...

The P-V phase transition of the FRW universe
European Physical Journal C: Particles and Fields, 2022 We define thermodynamic pressure P by work density W as the conjugate quantity of thermodynamic volume V from field equation. We derive the equations of state P=P(V, T) for the Friedmann–Robertson–Walker (FRW) universe in Einstein gravity and a modified ...

Maxwell-modified metric affine gravity
European Physical Journal C: Particles and Fields, 2021 We present a gauge formulation of the special affine algebra extended to include an antisymmetric tensorial generator belonging to the tensor representation of the special linear group.
