To stealth or not to stealth: Thermodynamics of stealth black holes
Athanasios Bakopoulos, Thanasis Karakasis, Eleftherios Papantonopoulos
Using Euclidean methods we investigate the thermodynamics of stealth black hole solutions, which are solutions that geometrically are indistinguishable from those of general relati…
Thermodynamics of black holes featuring primary scalar hair
Athanasios Bakopoulos, Nikos Chatzifotis, Thanasis Karakasis
In this work, we embark on the thermodynamic investigation concerning a family of primary charged black holes within the context of shift and parity symmetric Beyond Horndeski grav…
Exact black holes in string-inspired Euler-Heisenberg theory
Athanasios Bakopoulos, Thanasis Karakasis, Nick E. Mavromatos +2
We consider higher-order derivative gauge field corrections that arise in the fundamental context of dimensional reduction of String Theory and Lovelock-inspired gravities and obta…
Stealth Ellis Wormholes In Horndeski theories
Athanasios Bakopoulos, Nikos Chatzifotis, Cristian Erices +1
In this work we are revisiting the well studied Ellis wormhole solution in a generalized Horndeski theory motivated from the Kaluza-Klein compactification procedure of the more fun…
Large and Ultra-compact Gauss-Bonnet Black Holes with a Self-interacting Scalar Field
Athanasios Bakopoulos, Panagiota Kanti, Nikolaos Pappas
We consider the Einstein-scalar-Gauss-Bonnet theory, and study the case where a negative cosmological constant is replaced by a more realistic, negative scalar-field potential. We…
On the Existence of Solutions with a Horizon in Pure Scalar-Gauss-Bonnet Theories
Athanasios Bakopoulos, Panagiota Kanti, Nikolaos Pappas
We consider the Einstein-scalar-Gauss-Bonnet theory and assume that, at regimes of large curvature, the Ricci scalar may be ignored compared to the quadratic Gauss-Bonnet term. We…
