Statistical-Mechanics of Polymers with Distance Constraints
The ensemble of polymer conformations satisfying some distance constraints is studied using the replica approach. Dependence of the number of such conformations on the number of constraints is obtained. Possible implications of these results for the physics of polymer gels and the problem of protein structure reconstruction from NMR are discussed.
