摘要：

We consider anisotropic colloidal particles immersed in a solution of long, flexible, and non-adsorbing polymers: For the dumbbell shapes of recently synthesized particles consisting of two intersecting spheres, and for lens-shaped particles with spherical surfaces; we calculate the isotropic and anisotropic interaction parameters that determine the immersion free energy and the orientation-dependent depletion interaction between particles that are induced by the polymers. Exact results are obtained for ideal (random walk) polymer chains.
