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…
Quantum-Ordering Ambiguities in Weak Chern-Simons 4D Gravity and Metastability of the Condensate-Induced Inflation
Panagiotis Dorlis, Nick E. Mavromatos, Sotirios-Neilos Vlachos
In this work, we elaborate further on a 4D cosmological Running-Vacuum-type Model (RVM) of inflation that characterises string-inspired Chern-Simons (CS) gravity. It has been shown…
Condensate-Induced Inflation from Primordial Gravitational Waves in String-Inspired Chern-Simons Gravity
Panagiotis Dorlis, Nick E. Mavromatos, Sotirios-Neilos Vlachos
In this work, we elaborate further on a cosmological model of inflation that characterises Chern-Simons (CS) gravity models inspired from string theory. Such models are known to be…
Bypassing Bekenstein's no-scalar-hair theorem without violating the energy conditions
Panagiotis Dorlis, Nick E. Mavromatos, Sotirios-Neilos Vlachos
In this work we establish in a rigorous manner, and a model independent way, the conditions for bypassing Bekenstein's no-scalar-hair theorem for static, spherically symmetric, and…
