Torsion-induced axions in string theory, quantum gravity and the cosmological tensions
Nick E. Mavromatos, Panagiotis Dorlis, Sotirios-Neilos Vlachos
We discuss the role of torsion in string theory on inducing pseudoscalar degrees of freedom (axions), which in turn couple to (gravitational) Chern-Simons (CS) anomalous terms. Suc…
Gravitational Anomalies in string-inspired Cosmologies: from Inflation to Axion Dark Matter?
Nikolaos E. Mavromatos
In this talk, I review briefly a scenario for the evolution of a string-inspired cosmological model, in which condensates of primordial gravitational waves (GW), formed at the very…
Liouville Cosmology at Zero and Finite Temperatures
J. Ellis, N. E. Mavromatos, M. Westmuckett +1
We discuss cosmology in the context of Liouville strings, characterized by a central-charge deficit Q^2, in which target time is identified with (the world-sheet zero mode of the)…
Potentials between D-Branes in a Supersymmetric Model of Space-Time Foam
John Ellis, Nikolaos E. Mavromatos, Michael Westmuckett
We study a supersymmetric model of space-time foam with two stacks each of eight D8-branes with equal string tensions, separated by a single bulk dimension containing D0-brane part…
Brany Liouville Inflation
John Ellis, N. E. Mavromatos, D. V. Nanopoulos +1
We present a specific model for cosmological inflation driven by the Liouville field in a non-critical supersymmetric string framework, in which the departure from criticality is d…
A supersymmetric D-brane Model of Space-Time Foam
John Ellis, Nikolaos E. Mavromatos, Michael Westmuckett
We present a supersymmetric model of space-time foam with two stacks of eight D8-branes with equal string tensions, separated by a single bulk dimension containing D0-brane particl…
