DOI: 10.1103/physrevd.99.104018
Abstract: A new class of analytic charged spherically symmetric black hole solutions, which behave asymptotically as flat or (A)dS spacetimes, is derived for specific classes of $f(R)$ gravity, i.e., $f(R)=R-2\alpha\sqrt{R}$ and $f(R)=R-2\alpha\sqrt{R-8\Lambda}$, where $\Lambda$ is the… read more here.

DOI: 10.1134/s0202289317010121
Abstract: AbstractNew non-vacuum spherically symmetric solutions in (1+4)-dimensional space-time are derived using the field equations of f(T) theory, where T is the torsion scalar defined as $$T\mathop = \limits^{def} {T^\mu }_{\nu \rho }S_\mu ^{\nu \rho }$$T=defTμνρSμνρ… read more here.

DOI: 10.1140/epjc/s10052-020-08741-x
Abstract: In this work we extend the first law of thermodynamics to spherically symmetric black hole solutions in the context of scale-dependent gravity. After deriving generalized expressions for both the entropy and energy due to the… read more here.
