Axions, Black Holes and the Detection of Gravitons: from Astrophysics to Cosmology
Nick E. Mavromatos, Panagiotis Dorlis, Sarben Sarkar +1
We review a novel scenario for the emergence of spin-polarisation entangled squeezed graviton states from superradiant axionic clouds in the neighborhood of astrophysical rotating…
Dynamical-System analysis of single-axion monodromy inflation with periodically-modulated potentials
Panagiotis Dorlis, Nick E. Mavromatos, Sotirios-Neilos Vlachos +1
In this work, we study field theoretic systems of a single axion-like field with linear potentials modulated by cosine terms, allegedly induced by non-perturbative instanton config…
Superradiant Axionic Black-Hole Clouds as Seeds for Graviton Squeezing
Panagiotis Dorlis, Nick E. Mavromatos, Sarben Sarkar +1
It is shown that both, standard general relativity (GR) and Chern-Simons (CS) gravity, the latter containing chiral gravitational anomaly terms, seed the production of pairs of ent…
Inflation from Anomalies
Nick E. Mavromatos, Panagiotis Dorlis, Sotirios-Neilos Vlachos
We review a string-inspired model of inflation which is a consequence of condensates of chiral gravitational waves (GW) in the primordial Universe, leading in turn to a (approximat…
