Matter matters in Einstein-Cartan gravity
Georgios K. Karananas, Mikhail Shaposhnikov, Andrey Shkerin +1
We study scalar, fermionic and gauge fields coupled nonminimally to gravity in the Einstein-Cartan formulation. We construct a wide class of models with nondynamical torsion whose…
Islands in Linear Dilaton Black Holes
Georgios K. Karananas, Alex Kehagias, John Taskas
We derive a novel four-dimensional black hole with planar horizon that asymptotes to the linear dilaton background. The usual growth of its entanglement entropy before Page's time…
Aspects of spontaneous breaking of conformal invariance in the Fishnet CFT
Georgios K. Karananas
I will discuss spontaneous conformal symmetry breaking in the strongly -deformed limit of the supersymmetric Yang-Mills theory known as~\emph{Fishnet Conformal Fi…
Spontaneous Conformal Symmetry Breaking in Fishnet CFT
Georgios K. Karananas, Vladimir Kazakov, Mikhail Shaposhnikov
Quantum field theories with exact but spontaneously broken conformal invariance have an intriguing feature: their vacuum energy (cosmological constant) is equal to zero. Up to now,…
Scale-invariant alternatives to general relativity. III. The inflation--dark-energy connection
Santiago Casas, Georgios K. Karananas, Martin Pauly +1
We discuss the cosmological phenomenology of biscalar-tensor models displaying a maximally symmetric Einstein-frame kinetic sector and constructed on the basis of scale symmetry an…
On the strong-CP problem and its axion solution in torsionful theories
Georgios K. Karananas
Gravitational effects may interfere with the axion solution to the strong-CP problem. We point out that gravity can potentially provide a protection mechanism against itself, in th…
