Q-field from a 4D-brane: Cosmological constant cancellation and Minkowski attractor
F.R. Klinkhamer
TL;DR
This paper explores a 4D-brane model of q-theory, demonstrating how it dynamically cancels the cosmological constant and naturally evolves towards a Minkowski spacetime, providing insights into late-time cosmology.
Contribution
It introduces a 4D-brane realization of q-theory and analyzes its late-time cosmological behavior, showing dynamic cosmological constant cancellation and Minkowski attractor behavior.
Findings
Cosmological constant is dynamically canceled.
The universe evolves towards Minkowski spacetime.
The model provides a mechanism for late-time cosmological stability.
Abstract
A 4D-brane realization of -theory has been proposed a few years ago. The present paper studies the corresponding late-time cosmology and establishes the dynamic cancellation of an initial cosmological constant and an attractor behavior towards Minkowski spacetime.
