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 exist 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 acquire
stable late time accelerated solutions. We also discuss coupled tachyon field
with inverse square potential assuming linear coupling.Comment: 16 pages, 6 caption figures, 3 Tables, text, figure are added,
