Tachyon as a Dark Energy Source

TL;DR

This paper proposes a model where tachyons with non-minimal curvature coupling and inverse cubic potential evolve into cold dark matter, offering a potential solution to the cosmic coincidence problem.

Contribution

It introduces a novel tachyon-based dark energy model with specific couplings and potentials that explains the transition to cold dark matter.

Findings

Dark energy decays into cold dark matter in late universe

Model addresses the cosmic coincidence problem

Tachyon dynamics with non-minimal coupling are viable for cosmology

Abstract

It is demonstrated that dark energy, driven by tachyons having non-minimal coupling with curvature and self-interacting inverse cubic potential, decays to cold dark matter in the late universe. It is found that this penomenon yields a solution to `` cosmic coincidence problem''.
