Dynamics of Interacting Tachyonic Teleparallel Dark Energy

Abstract EN

We consider a tachyon scalar field which is nonminimally coupled to gravity in the framework of teleparallel gravity.

We analyze the phase-space of the model, known as tachyonic teleparallel dark energy, in the presence of an interaction between dark energy and background matter.

We find that although there exist some late-time accelerated attractor solutions, there is no scaling attractor.

So, unfortunately interacting tachyonic teleparallel dark energy cannot alleviate the coincidence problem.
