  The Dynamic Density Functional (DDF) theory and standard Brownian dynamics
simulations (BDS) are used to study the drifting effects of a colloidal
particle in a polymer solution, both for ideal and interacting polymers. The
structure of the stationary density distributions and the total induced current
are analyzed for different drifting rates. We find good agreement with the BDS,
which gives support to the assumptions of the DDF theory. The qualitative
aspect of the density distribution are discussed and compared to recent results
for driven colloids in one-dimensional channels and to analytical expansions
for the ideal solution limit.
