FLORY THEORY REVISITED by
The Flory theory for a single polymer chain is derived as the lowest order of a cumulant expansion. In this approach, the full original Flory free energy (including the logarithmic term), is recovered. The prefactors of the elastic and repulsive energy are calculated from the microscopic parameters. The method can be applied to other types of monomer-monomer interactions, and the case of a sing...
متن کاملFlory theory for polymers.
We review various simple analytical theories for homopolymers within a unified framework. The common guideline of our approach is the Flory theory, and its various avatars, with the attempt at being reasonably self-contained. We expect this review to be useful as an introduction to the topic at the graduate student level.
متن کاملConformal field theory of the Flory model of polymer melting.
We study the scaling limit of a fully packed loop model in two dimensions, where the loops are endowed with a bending rigidity. The scaling limit is described by a three-parameter family of conformal field theories, which we characterize via its Coulomb-gas representation. One choice for two of the three parameters reproduces the critical line of the exactly solvable six-vertex model, while ano...
متن کاملFlory theory for conductivity of random resistor networks
2014 We develop a Flory theory for the problem of conductivity in a d-dimensional random resistor network. We find that the conductivity exponent t is related to the fractal dimensionality df according to the Alexander-Orbach conjecture t = d 2 + df/2, where consistently with Flory theory df = (d + 2)/2 for percolation and df = 2(d + 2)/5 for lattice animals. The results are in excellent agreem...
متن کاملCognitive Metaphor Theory Revisited
This paper provides a framework which, being compatible with Lakoff and Johnson’s theory (1980), allows a description of metaphoric verbal utterances. The development of this theoretical expansion is encouraged by Lakoff and Johnson’s distinction between nonliteral and literal metaphoric expressions, and by the fact that they do not provide an explanation of the nonliteral metaphoric use of exp...
