In this paper, we apply the dynamical analysis to a
coupled phantom field with scaling potential taking particular
forms of the coupling (linear and combination of linear), and
present phase space analysis. We investigate if there exists
a late time accelerated scaling attractor that has the ratio of
dark energy and dark matter densities of the order one. We
observe that the scrutinized couplings cannot alleviate the
coincidence problem, however, they acquire stable late time
accelerated solutions. We also discuss a coupled tachyon field
with inverse square potential assuming linear coupling.
