Fundamental scalar fields and the dark side of the universe

TL;DR

This paper proposes that fundamental scalar fields, derived from geometrical principles, can explain dark energy and dark matter as induced by specific scalar fields with distinct physical properties.

Contribution

It introduces a geometrically motivated framework where two scalar fields account for dark energy and dark matter, linking them to fundamental cosmological phenomena.

Findings

Dark energy field has a tiny Hubble mass scale (~ 10^-33 eV).

Dark matter is modeled as a scalar conglomerate of primordial neutrinos.

Scalar fields can be induced by spacetime geometry according to the Papapetrou algorithm.

Abstract

Starting with geometrical premises, we infer the existence of fundamental cosmological scalar fields. We then consider physically relevant situations in which spacetime metric is induced by one or, in general, by two scalar fields, in accord with the Papapetrou algorithm. The first of these fields, identified with dark energy, has exceedingly small but finite (subquantum) Hubble mass scale (~ 10^-33 eV), and might be represented as a neutral superposition of quasi-static electric fields. The second field is identified with dark matter as an effectively scalar conglomerate composed of primordial neutrinos and antineutrinos in a special tachyonic state.
