Supersymmetry approach to the random heteropolymer theory
The effective equation of motion that describes the different monomer
alternation along the heteropolymer chain is proposed. On this basis the
supersymmetry field scheme is built up to analyze memory and ergodicity
breaking effects.Comment: 10 pages, 1 figur
Two Simple Approaches to Sol-Gel Transition
We represent a theory of polymer gelation as an analogue of liquid-glass
transition in which elastic fields of stress and strain shear components appear
spontaneously as a consequence of the cross-linking of macromolecules. This
circumstance is explained on the basis of obvious combinatoric arguments as
well as a synergetic Lorenz system, where the strain acts as an order
parameter, a conjugate field is reduced to the elastic stress, and the number
of cross-links is a control parameter. Both the combinatoric and synergetic
approaches show that an anomalous slow dependence of the shear modulus on the
number of cross-links is obtained.Comment: 10 pages, LaTe
