Non-Riemannian Volume Elements Dynamically Generate Inflation
David Benisty, Eduardo Guendelman, Emil Nissimov +1
Our primary objective is the formulation of a plausible cosmological inflationary model entirely in terms of a pure modified gravity without any a priori matter couplings within th…
Running Dark Energy and Dark Matter from Dynamical Spacetime
Shreya Banerjee, David Benisty, Eduardo I. Guendelman
Running Dark Energy and Dark Matter models are candidates to resolve the Hubble constant tension. However the model does not consider a Lagrangian formulation directly. In this pap…
The Scale Factor Potential Approach to Inflation
David Benisty, Eduardo I. Guendelman, Emmanuel N. Saridakis
We propose a new approach to investigate inflation in a model-independent way, and in particular to elaborate the involved observables, through the introduction of the "scale facto…
Dynamically generated inflationary two-field potential via non-Riemannian volume forms
David Benisty, Eduardo I. Guendelman, Emil Nissimov +1
We consider a simple model of modified gravity interacting with a single scalar field with weakly coupled exponential potential within the framework of non-Riemannian spacetime…
Dynamically Generated Inflation from Non-Riemannian Volume Forms
David Benisty, Eduardo Guendelman, Emil Nissimov +1
We propose a simple modified gravity model without any initial matter fields in terms of several alternative non-Riemannian spacetime volume elements within the metric (second orde…
Dark energy and dark matter unification from dynamical space time: observational constraints and cosmological implications
Fotios K. Anagnostopoulos, David Benisty, Spyros Basilakos +1
A recently proposed Dynamical Space-time Cosmology (DSC) that unifies dark energy and dark matter is studied. The general action of this scenario includes a Lagrange multiplier, wh…
