Fermionic Tachyons as a Source of Dark Energy

TL;DR

This paper proposes a model where a self-interacting fermionic tachyon field drives the universe's accelerated expansion, potentially explaining dark energy as a cosmological constant-like effect.

Contribution

It introduces a novel fermionic tachyon field model with a specific self-interaction potential that can produce late-time acceleration consistent with dark energy observations.

Findings

Fermionic tachyon field induces accelerated expansion.

Late-time behavior approaches a constant, mimicking cosmological constant.

Model aligns with observed dark energy effects.

Abstract

A model for the universe on the basis of a self interacting fermionic tachyon field is investigated here. It is shown that, devising a self interaction potential of a proper form, the fermionic tachyon field is capable of producing an accelerating expansion that at late time tends to a constant value which is in consistence with the cosmological constant. This way the introduced fermionic tachyon field can be interpreted as the source of dark energy.
