Polytropic wormholes
Remo Garattini, Emmanuel N. Saridakis, Athanasios G. Tzikas
Traversable wormholes in general relativity require non-standard matter sources, making the identification of physically motivated equations of state particularly important. We inv…
Branch structure and nonextensive thermodynamics of Kalb-Ramond-ModMax black holes: observational signatures
Erdem Sucu, Izzet Sakalli, Emmanuel N. Saridakis
Motivated by the low-energy effective action of heterotic string theory, where the Kalb-Ramond (KR) two-form and nonlinear gauge corrections arise simultaneously, we investigate a…
Traversable Wormhole Solutions in massive gravity
Alexandre Landry, Yassine Sekhmani, Sunil K Maurya +2
We study traversable wormhole geometries in an teleparallel framework augmented by a perturbative de Rham-Gabadadze-Tolley (dRGT) graviton-mass term. Adopting the static, sp…
Rotating Black Holes with Primary Scalar Hair: Shadow Signatures in Beyond Horndeski Gravity
Kourosh Nozari, Milad Hajebrahimi, Sara Saghafi +2
The Event Horizon Telescope (EHT) image of M87* provides a direct test of strong-field gravity, measuring an angular shadow diameter and a circularit…
3-dimensional charged black holes in gravity
G. G. L. Nashed, Emmanuel N. Saridakis
We present new exact charged black hole solutions in (2+1) dimensions within the framework of gravity, where denotes the non-metricity scalar. By considering a cubic…
Black Hole Entropy and Complexity Growth in Horndeski Gravity within the AdS/BCFT Framework
Fabiano F. Santos, Behnam Pourhassan, Emmanuel N. Saridakis
This work investigates the connection between quantum complexity and gravitational dynamics within the framework of Horndeski gravity, extending the AdS/BCFT correspondence to incl…
