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…
Microstructure of charged AdS black hole via criticality
Amin Dehyadegari, Ahmad Sheykhi, Shao-Wen Wei
We suggest a new thermodynamic curvature, constructed via adiabatic compressibility, for examining the internal microstructure of charged black holes in an anti-de Sitter (AdS) bac…
Critical behavior of charged dilaton black holes in AdS space
Amin Dehyadegari, Ahmad Sheykhi
We revisit critical behaviour and phase structure of charged anti-deSitter (AdS) dilaton black holes for arbitrary values of dilaton coupling , and realize several novel phase b…
Reentrant phase transition of Born-Infeld-AdS black holes
Amin Dehyadegari, Ahmad Sheykhi
We investigate thermodynamic phase structure and critical behaviour of Born-Infeld (BI) black holes in an anti-de Sitter (AdS) space, where the charge of the system can vary and th…
Critical behaviour and microscopic structure of charged AdS black holes via an alternative phase space
Amin Dehyadegari, Ahmad Sheykhi, Afshin Montakhab
It has been argued that charged Ads black holes have similar thermodynamic behavior as the Van der Waals fluid system, provided one treats the cosmological constant as a thermodyna…
