Magnetically Charged Euler-Heisenberg Black Holes with Scalar Hair
Thanasis Karakasis, George Koutsoumbas, Andri Machattou +1
We study the Einstein-Euler-Heisenberg theory in the presence of a self interacting scalar field, minimally coupled to gravity. We solve analytically the field equations for the ma…

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…
