Lattice Models of Polymers by Carlo Vanderzande download in ePub, pdf, iPad

This article needs additional citations for verification. Lattice Models of Polymers Book This is a comprehensive introduction to lattice models of polymers, an important topic both in the theory of critical phenomena and the modeling of polymers. The models have their origin in the atomistic representations of matter on one hand, and in the truss-type systems in engineering on the other. Physical lattice models frequently occur as an approximation to a continuum theory, either to give an ultraviolet cutoff to the theory to prevent divergences or to perform numerical computations.

The paper evolves by first giving a rather detailed presentation of one-dimensional and planar lattice models for classical continua. More generally, lattice gauge theory and lattice field theory are areas of study. At a critical threshold pc, large clusters and long-range connectivity first appears, and this is called the percolation threshold.

One can also consider continuum systems, such as overlapping disks and spheres placed randomly, or the negative space Swiss-cheese models. This book will be valuable for graduate students and researchers working in statistical mechanics, theoretical physics and polymer physics. The exact solution to many of these models when they are solvable includes the presence of solitons. For a continuum system, random occupancy corresponds to the points being placed by a Poisson process. We then return to planar lattice models made of beams, which are a discrete counterpart of non-classical continua.

Over the last several decades, a tremendous amount of work has gone into finding exact and approximate values of the percolation thresholds for a variety of these systems. Lattice models are also used to simulate the structure and dynamics of polymers. The first two chapters introduce the basic theory of random, directed and self-avoiding walks. Exact thresholds are only known for certain two-dimensional lattices that can be broken up into a self-dual array, such that under a triangle-triangle transformation, the system remains the same.
