Generalized Tachyonic Teleparallel cosmology
  In this paper we propose a new dark energy model in the teleparallel
alternative of general relativity, by considering a generalized non--minimal
coupling of a tachyonic scalar field with the teleparallel boundary term.
Within the framework of teleparallel gravity, the boundary coupling term is
associated with the divergence of the torsion vector. Considering the linear
stability technique for various potentials and couplings, we have analyzed the
dynamical properties of the present tachyonic dark energy model in the phase
space, uncovering the corresponding essential dynamical features. Our study of
the phase space structure revealed that for a specific class of potential
energy, this model exhibits various critical points which are related to
different cosmological behaviors, such as accelerated expansion and scaling
solutions, determining the existence conditions and the corresponding physical
features.
