Thermodynamic Phase Transitions in Einstein-Maxwell-Scalar-Gauss-Bonnet Gravity
Cristián Erices, Stella Kiorpelidi
Although asymptotically flat black holes generically lack thermodynamic phase transitions, we show that curvature-induced scalarization of electrically charged black holes in Einst…
Scalarization of the Reissner-Nordström black hole with higher derivative gauge field corrections
Stella Kiorpelidi, Thanasis Karakasis, George Koutsoumbas +1
We discuss spontaneous scalarization of the Reissner-Nordström black hole in the presence of higher derivative gauge field corrections that arise in the context of string, as well…
Topological Black Holes with curvature induced scalarization in the extended scalar-tensor theories
Stella Kiorpelidi, George Koutsoumbas, Andri Machattou +1
We study the perturbative behaviour of topological black holes in the presence of a cosmological constant and a scalar field coupled to the Gauss-Bonnet term. We calculate both ana…
Cosmological perturbations in modified teleparallel gravity models: Boundary term extension
Sebastian Bahamonde, Viktor Gakis, Stella Kiorpelidi +3
Teleparallel gravity offers a new avenue in which to construct gravitational models beyond general relativity. While teleparallel gravity can be framed in a way to be dynamically e…
Spontaneous Holographic Scalarization of Black Holes in Einstein-Scalar-Gauss-Bonnet Theories
Hong Guo, Stella Kiorpelidi, Xiao-Mei Kuang +3
We holographically investigate the scalarization in the Einstein-Scalar-Gauss-Bonnet gravity with a negative cosmological constant. We find that instability exists for both Schwarz…
Charged Gauss-Bonnet black holes with curvature induced scalarization in the extended scalar-tensor theories
Daniela D. Doneva, Stella Kiorpelidi, Petya G. Nedkova +2
Recently new scalarized black hole solutions were constructed in the extended scalar-tensor-Gauss-Bonnet gravity, where the scalar field is sourced by the curvature of the spacetim…
Superradiance Effect of a Black Hole Immersed in an Expanding Universe
Stella Kiorpelidi, Konstantinos Ntrekis, Eleftherios Papantonopoulos
We studied the superradiance effect of a charge black hole immersed in an expanding Universe. We considered a test massive charged scalar field scattered off the horizon of the cha…
