Cosmic evolution in f(T) gravity theory

TL;DR

This paper explores how modified f(T) gravity can model the universe's evolution from early emergence to late-time acceleration, including thermodynamical aspects, using phenomenological functions and cosmological solutions.

Contribution

It demonstrates that specific f(T) functions can produce a continuous cosmic evolution and analyzes the thermodynamics within this gravity framework.

Findings

Cosmological solutions describe different universe phases.

Proper parameter choices enable continuous evolution from emergence to acceleration.

Thermodynamical analysis supports the viability of f(T) gravity.

Abstract

The paper deals with cosmology in modified f(T) gravity theory. With some phenomenological choices for the function f(T) it is possible to have cosmological solutions describing different phases of the evolution of the Universe for the homogeneous and isotropic FLRW model. By proper choice of the parameters involved in the function $f(T)$ and also in the cosmological solutions it is shown that a continuous cosmic evolution starting from the emergent scenario to the present late time acceleration is possible. Finally thermodynamical analysis of f(T) gravity is presented.
