Tachyonic Teleparallel Dark Energy in Phase Space

Tachyonic Teleparallel Dark Energy in Phase Space

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...
