Ghost Dark Energy in the Modified Kaniadakis Cosmology
A. Dezhakam, A. Sheykhi, A. Dehyadegari
We investigate ghost dark energy (GDE) in a cosmological framework derived from Kaniadakis entropy. By applying the first law of thermodynamics to the FRW apparent horizon, we obta…

Modified Entropy from Action Principle
A. Dehyadegari, A. Sheykhi
We propose a modified gravity theory by extending the Einstein-Hilbert action with an arbitrary function of the Ricci scalar and the Kretschmann scalar invariants. The resulting mo…

New Black hole Solutions in Gravity
A. Dehyadegari, A. Sheykhi
We investigate static and spherically symmetric vacuum solutions in the symmetric teleparallel modified theory of gravity. Starting from a recently proposed classif…
