Abstract:
In this work we show that the tachyons in teleparallel gravity with nonminimal boundary couplings represent a possible dark energy cosmological model which can explain the current acceleration of the Universe. By using linear stability method, we discuss the effects of nonminimal couplings into the phase space structure, analyzing the cosmological validity of such an exotic model. Our presentation is based on our recent paper [1].
