Connecting Early Dark Energy to Late Dark Energy by the Diluting Matter Potential
Eduardo I. Guendelman, Ramon Herrera, Pedro Labrana
In this work we study a scale invariant gravity theory containing two scalar fields, dust particles and a measure defined from degrees of freedom independent of the metric. The int…
Dynamical String Tension Theories with target space scale invariance SSB and restoration
Eduardo Guendelman
The string and brane tensions do not have to be put in by hand, they can be dynamically generated, as in the case when we formulate string and brane theories in the modified measur…
Exploring Cosmological Implications of the Modified Raychaudhuri Equation in Non-Gravitating Vacuum Energy Theory
Arijit Panda, Eduardo Guendelman, Goutam Manna
This article investigates the modified Raychaudhuri Equation (RE) in the context of Non-Gravitating Vacuum Energy (NGVE) theory and its implications for various cosmological charac…
Unifying Inflation, dark energy and dark matter with a scalar field and exotic fermions
Eduardo Guendelman, Ramon Herrera
In this paper we consider a new approach to unify inflation and the late universe with dark energy and dark matter formulated in a model that includes a non-Riemannian metric indep…
White Paper and Roadmap for Quantum Gravity Phenomenology in the Multi-Messenger Era
R. Alves Batista, G. Amelino-Camelia, D. Boncioli +101
The unification of quantum mechanics and general relativity has long been elusive. Only recently have empirical predictions of various possible theories of quantum gravity been put…
