Reconstructing gravity from generalized entropies: exact Lagrangians
Ankit Anand, Sahil Devdutt, Kimet Jusufi +2
Generalized horizon entropies are widely used as theoretical modifications of the Bekenstein-Hawking area law, but through the Wald construction they may also encode modifications…
Reconstructing the generalized Barrow holographic dark energy with physics-informed neural networks
Spyros Basilakos, Andronikos Paliathanasis, Emmanuel N. Saridakis +1
Barrow holographic dark energy connects cosmic acceleration with possible quantum-gravitational deformations of horizon entropy, encoded in the Barrow exponent . If such effects…
Early- and late-time constraints on Wald-Gauss-Bonnet topological dark energy and implications for the and tensions
Stylianos A. Tsilioukas, Fotios K. Anagnostopoulos, Spyros Basilakos +2
The persistent and tensions motivate the search for new dark-energy mechanisms capable of modifying the late-time expansion history while preserving the successful earl…
Unified dark sector and Hubble-tension alleviation in scalar-vector-tensor gravity
Kimet Jusufi, Amir A. Khodahami, Ahmad Sheykhi +2
We investigate a scalar-vector-tensor theory in which matter is minimally coupled to a Jordan-frame metric , while a massive vector sector interacts with…
Thermodynamically massless Simpson-Visser black holes
Thanasis Karakasis, Emmanuel N. Saridakis, Zi-Yu Tang
In this work we scrutinize the thermodynamic properties of the Simpson-Visser (SV) spacetime. Working within Einstein gravity coupled to nonlinear electrodynamics (NLED) and a scal…
Modified Teleparallel Gravity, DESI BAO and the Tension
Mariam Bouhmadi-López, Carlos G. Boiza, Maria Petronikolou +1
We investigate whether late-time modifications of gravity in the teleparallel framework can impact the current tension in the Hubble constant , focusing on cosmology as…
Emergence of ER=EPR from non-local gravitational energy
Kimet Jusufi, Francisco S. N. Lobo, Emmanuel N. Saridakis +1
We construct a class of wormhole geometries supported by the non-local gravitational self-energy that regularizes the particle and black-hole sectors of spacetime. Using this frame…
Topological dark energy from spacetime foam: A challenge for CDM
Fotios K. Anagnostopoulos, Stylianos A. Tsilioukas, Emmanuel N. Saridakis
Using only the standard considerations of spacetime foam and the Euclidean Quantum Gravity techniques known long ago, we result to a model of Topological Dark Energy (TDE) that com…
Reissner-Nordström and Kerr-like solutions in Finsler-Randers Gravity
Georgios Miliaresis, Konstantinos Topaloglou, Ioannis Ampazis +5
In a previous study we investigated the spherically symmetric Schwarzschild and Schwarzschild-de Sitter solutions within a Finsler-Randers-type geometry. In this work we extend our…
Addressing and tensions within cosmology
Carlos G. Boiza, Maria Petronikolou, Mariam Bouhmadi-López +1
We investigate the viability of gravity as an alternative framework to address the and tensions in cosmology. Focusing on three representative models, we…
Observational implications of Wald-Gauss-Bonnet topological dark energy
Maria Petronikolou, Fotios K. Anagnostopoulos, Stylianos A. Tsilioukas +2
We investigate the observational implications of Wald--Gauss--Bonnet (WGB) topological dark energy, a modified cosmological framework derived from the gravity-thermodynamics conjec…
Topological dark energy from black-hole formations and mergers through the gravity-thermodynamics approach
Stylianos A. Tsilioukas, Nicholas Petropoulos, Emmanuel N. Saridakis
We apply the gravity-thermodynamics approach in the case of Einstein-Gauss-Bonnet theory, and its corresponding Wald-Gauss-Bonnet entropy, which due to the Chern-Gauss-Bonnet theor…
