A bulk perturbation in an Alexander brush

Research output: Contribution to journalArticlepeer-review

We consider the effects of a small, intruding object in the bulk of a flat Alexander polymer brush in a melt state. A pointlike object creates a pressure field that has a quadrupolar form at short distances but decays exponentially away from the source. The induced surface deformation also decays exponentially away from the source, and in both cases, the decay length is of the order of the brush thickness. We also discuss the interaction between two immersed objects.
