Random Two-Component One-Dimensional Ising Model for Heteropolymer Melting

Abstract

Heteropolymer melting corresponds to a low-temperature phase transition in a one-dimensional two-component Ising model. A leading-order approximation for an additive physical quantity in the melting region is introduced; it is intimately connected with the microscopic statistical herteropolymer structure. This allows one to derive the heteropolymer distribution function (over the length and composition of the sections) directly from experimental data.
