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…
Cosmology of fermionic dark energy coupled to curvature
David Benisty
A formulation of cosmology driven by fermions is studied. Assumption that the expectation value of the fermion bilinear is non-zero simplifies the homogeneous solution of the D…
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…
Covariant Canonical Quantization
P. Liebrich
A formulation of Covariant Canonical Quantization is discussed, which works on an extended Hilbert space and reduces to conventional canonical quantization when constraining to the…
