Statistical mechanics of pseudoknot polymers

Journal of Chemical Physics, 2003
We present the theory for the conformational free energies of RNA molecules and other polymers that have pseudoknots. We derive an expression for the partition function by counting conformational loops that we call pseudoknot core units, using the theory of self-avoiding walks.

Statistical mechanics of polymers with distance constraints

Journal of Chemical Physics, 1994
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.

Statistical mechanics and topology of polymer chains

Nature, 1975
The statistical-mechanical treatment of closed polymer chains based on algebraic topology is proposed. Using the Monte-Carlo method numerical results were obtained for the probability to knot formation during random closing of polymer chains of different length.

The statistical mechanics of entangled polymers

Journal of Physics A: General Physics, 1972
A particular model of the entanglement of two polymers is studied in which one is taken to have a solenoidal configuration whilst the other is a random llk. The various classes of configurations are analysed, and the probability distribution of the random flight polymer is calculated in detail when it lies in the same topological class as the axis of ...

Statistical Mechanics of Directed Polymer Melts

Europhysics Letters (EPL), 1991
Solutions of variable-length directed polymers are studied via a mapping onto the quantum mechanics of bosons with an external source in two dimensions. The theory is applicable, in particular, to entangled polymer nematics. We calculate the structure function of these systems, and the renormalized Frank constants.
