Query: Like-Charge Colloid-Polyelectrolyte Complexation   We investigate the complexation of a highly charged sphere with a long
flexible polyelectrolyte, \textit{both negatively charged} in salt free
environment. Electroneutrality is insured by the presence of divalent
counterions. Using molecular dynamics (MD) within the framework of the
primitive model, we consider different Coulomb coupling regimes. At strong
Coulomb coupling we find that the adsorbed chain is always confined to the
colloidal surface but forms different conformations that depend on the linear
charge density of the chain. A mechanism involving the polyelectrolyte
\textit{overcharging} is proposed to explain these structures. At intermediate
Coulomb coupling, the chain conformation starts to become three-dimensional,
and we observe multilayering of the highly charged chain while for lower charge
density the chain wraps around the colloid. At weak Coulomb coupling,
corresponding to an aqueous solvent, we still find like-charge complexation. In
this latter case the chain conformation exhibits loops.
