Title:
Statistical Mechanics of Anchored Polymer Chains
Speaker:
Abstract:
We review some aspects of the statistical mechanics of several models of polymer chains attached to a wall, and the related entropic forces. These include the Gaussian chain, the freely-jointed chain, the worm-like chain and the framed DNA chain. Applications to protein translocation and to DNA pulling and twisting experiments will be briefly described. We shall end with the interesting case of a freely-jointed chain in a half-space, which happens to have non-trivial combinatorics and symplectic structure.
