Tachyonic Teleparallel Dark Energy in Phase Space

Abstract EN

Recently, nonminimal coupling between a noncanonical scalar field and gravity in the framework of teleparallelism has been proposed.

Noncanonical scalar field is tachyon field, and the model is known as tachyonic teleparallel dark energy.

Here, we perform a dynamical analysis of the model, find its critical points, and study their stability.

We find that all the critical points are dark energy dominated solutions corresponding to an accelerating universe.

It is also shown that there exist two critical lines which are stable attractors of the model.
