Analysis of observables in FLRW spacetime
P. Fernandez de Cordoba, S. Gavasso, J. M. Isidro
We consider a positively curved FLRW spacetime as a background in which a nonrelativistic quantum particle propagates according to the Schroedinger equation. The probability fluid…
Gravitation as a Statistical Theory on the Light Cone
José M. Isidro, Claudio F. Paganini, Alessandro Pesci
In this paper, we will explore Padmanabhan's mesoscopic, statistical approach to gravity [62] with a twist. The general picture of his approach is that spacetime is made of large n…
Theoretically motivated dark electromagnetism as the origin of relativistic MOND
Felix Finster, J. M. Isidro, Claudio F. Paganini +1
The present paper is a modest attempt to initiate the research program outlined in this abstract. We propose that general relativity and relativistic MOND (RelMOND) are analogues o…
A Mechanism for Dark Matter and Dark Energy in the Theory of Causal Fermion Systems
Felix Finster, J. M. Isidro
It is shown that the theory of causal fermion systems gives rise to a novel mechanism for dark matter and dark energy. This mechanism is first worked out for cubical subsets of Min…
On the cosmological constant as a quantum operator
P. Fernandez de Cordoba, R. Gallego Torrome, S. Gavasso +1
We regard the cosmological fluid within an exponentially expanding FLRW spacetime as the probability fluid of a nonrelativistic Schroedinger field. The scalar Schroedinger particle…
On the cosmological constant of flat FLRW spacetime
P. Fernandez de Cordoba, R. Gallego Torrome, S. Gavasso +1
We consider an exponentially expanding, flat, Friedmann-Lemaitre-Robertson-Walker (FLRW) Universe filled with a free Schroedinger field. The probability fluid of the latter is used…
Hyperbolic space in the Newtonian limit: the cosmological constant
J. C. Castro-Palacio, P. Fernandez de Cordoba, R. Gallego Torrome +1
The cosmological constant and the Boltzmann entropy of a Newtonian Universe filled with a perfect fluid are computed, under the assumption that spatial sections are copies of 3-dim…
On the holographic bound in Newtonian cosmology
P. Fernandez de Cordoba, J. M. Isidro
The holographic principle sets an upper bound on the total entropy content of the Universe. Within the limits of a Newtonian approximation, a quantum-mechanical model is presented…
