Noether Symmetry in Newtonian Dynamics and Cosmology
E. I. Guendelman, E. Zamlung, D. Benisty
A new symmetry for Newtonian Dynamics is analyzed, this corresponds to going to an accelerated frame, which introduces a constant gravitational field into the system and subsequent…
The Local Group as a test system for Modified Newtonian Dynamics
David Benisty, Eduardo I. Guendelman
The Local Group (LG) is {an appropriate} test system for Modified Newtonian Dynamics, since the acceleration of M31 galaxy is fully in the deep MOND regime . We model th…
Quintessential Inflation from Lorentzian Slow Roll
David Benisty, Eduardo I. Guendelman
From the assumption that the slow roll parameter has a Lorentzian form as a function of the e-folds number , a successful model of a quintessential inflation is obtained, as…
Non-Canonical Volume-Form Formulation of Modified Gravity Theories and Cosmology
David Benisty, Eduardo I. Guendelman, Alexander Kaganovich +2
A concise description is presented of the basic features of the formalism of non-canonical spacetime volume-forms and its application in modified gravity theories and cosmology. Th…
Instant preheating in a scale invariant two measures theory
Eduardo I. Guendelman, Ramon Herrera, Pedro Labrana
The instant preheating mechanism in the framework of a scale invariant two measures theory is studied. We introduce this mechanism into a non oscillating inflationary model as anot…
Lorentzian Quintessential Inflation
David Benisty, Eduardo I. Guendelman
From the assumption that the slow roll parameter has a Lorentzian form as a function of the e-folds number , a successful model of a quintessential inflation is obtained. Th…
Quintessential Inflation with Dynamical Higgs Generation as an Affine Gravity
David Benisty, Eduardo Guendelman, Emil Nissimov +1
First, we propose a scale-invariant modified gravity interacting with a neutral scalar "inflaton" and a Higgs-like SU(2)xU(1) iso-doublet scalar field based on the formalism of non…
CDM as a Noether Symmetry in Cosmology
David Benisty, Eduardo I. Guendelman, Emil Nissimov +1
The standard CDM model of cosmology is formulated as a simple modified gravity coupled to a single scalar field ("darkon") possessing a non-trivial hidden nonlinear Noether symm…
Dynamically Generated Inflationary Lambda-CDM
David Benisty, Eduardo Guendelman, Emil Nissimov +1
Our primary objective is to construct a plausible unified model of inflation, dark energy and dark matter from a fundamental Lagrangian action first principle, where all fundamenta…
