Thermal Stability and QNMs of a Hairy Black Hole in the Presence of a Monopole Field
George Koutsoumbas, Andri Machattou, Eleftherios Papantonopoulos
We study the stability of a generalization of the GHS-GM black hole in the presence of a dilaton and a monopole field. We find that the thermal behaviour of system depends on the s…
Formation of Bound States in Quintessence Alternative Theories
George Koutsoumbas, Andri Machattou, Eleftherios Papantonopoulos
We study the formation and behaviour of bound states formed outside the horizon of a black hole in the presence of quintessence matter. Calculating the Regge and Wheeler potential…
Kinetic coupling and dark matter on the lattice
K. Farakos, V. Iconomou, G. Koutsoumbas
We study a system coupled to scalar fields. Initially the model is studied in a novel continuum formulation and study of the appropriate diagonalizations is perf…
On internal mechanical properties of Electroweak Magnetic Monopoles and their effects on stability
K. Farakos, G. Koutsoumbas, Nick E. Mavromatos +1
By considering properties of the energy-momentum tensor of the electroweak magnetic monopole and its Born-Infeld extension, we attempt to make comments on the stability of these co…
Effective Abelian Lattice Gauge Field Theories for scalar-matter-monopole interactions
K. Farakos, G. Koutsoumbas, Nick E. Mavromatos
We present a gauge and Lorentz invariant effective field theory model for the interaction of a charged scalar matter field with a magnetic monopole source, described by an external…
Motion of particles around a magnetically charged Euler-Heisenberg black hole with scalar hair and the Event Horizon Telescope
Dionysios P. Theodosopoulos, Thanasis Karakasis, George Koutsoumbas +1
We study the motion of uncharged particles and photons in the background of a magnetically charged Euler-Heisenberg (EH) black hole (BH) with scalar hair. The spacetime can be asym…
