Cosmological Evolution for Dark Energy Models in f(T) Gravity

TL;DR

This paper explores the evolution of dark energy in f(T) gravity using an anisotropic universe model, analyzing the equation of state and energy density to understand cosmic acceleration and phase transitions.

Contribution

It investigates dark energy behavior in f(T) gravity within an anisotropic universe, highlighting phase transitions and comparing results to standard cosmology.

Findings

Universe transitions between phantom and non-phantom phases for most f(T) models.

Exponential and logarithmic f(T) models do not exhibit phase transition.

Results are consistent with those in the FRW universe model.

Abstract

In this paper, we investigate the behavior of equation of state parameter and energy density for dark energy in the framework of f(T) gravity. For this purpose, we use anisotropic LRS Bianchi type I universe model. The behavior of accelerating universe is discussed for some well-known f(T) models. It is found that the universe takes a transition between phantom and non-phantom phases for f(T) models except exponential and logarithmic models. We conclude that our results are relativity analogous to the results of FRW universe.
