A Unified Model of Dark Energy Based on the Mandelstam-Tamm Uncertainty Relation

TL;DR

This paper proposes a novel approach to understanding dark energy by applying the Mandelstam-Tamm uncertainty relation, suggesting it could be an effective, universal contribution influencing the universe's evolution and cosmological parameters.

Contribution

It introduces a new theoretical framework linking quantum uncertainty relations to dark energy, providing a unified model that impacts cosmological understanding.

Findings

Derives an effective Lambda-term from quantum uncertainty principles.

Suggests the Lambda-term is a universal feature throughout cosmic history.

Reevaluates cosmological parameters like the age of the Universe.

Abstract

It is commonly recognized now that Dark Energy (Lambda-term) is of crucial importance both at the early (inflationary) stage of cosmological evolution and at the present time. However, little is known about its nature and origin till now. In particular, it is still unclear if Lambda-term is a new fundamental constant or represents just an effective contribution from the underlying field theory. Here, we show that a quite promising and universal approach to this problem might be based on the Mandelstam-Tamm uncertainty relation of quantum mechanics. As a result, we get the effective Lambda-term that is important throughout the entire history of the Universe. Besides, such an approach requires a substantial reconsideration of some other cosmological parameters, e.g., the age of the Universe.
