Single chain structure in thin polymer films: corrections to Flory's and Silverberg's hypotheses
TL;DR: In this paper, a Monte Carlo simulation of the bond fluctuation model of polymer melts confined between two hard structureless walls is investigated, and the authors demonstrate that for ultrathin films where the thickness, H, is smaller than the excluded volume screening length (blob size), ξ, the chain size parallel to the walls diverges logarithmically, R2/2N≈b2+clog(N) with c~1/H.

TL;DR: In this paper, the authors show that both static and dynamical correlations arise on distances $r \gg \xi$ and that these correlations are scale-free and do not depend explicitly on the compressibility of solution.

Phase behaviour of quasi-block copolymers: A DFT-based Monte-Carlo study
TL;DR: In this article, a mesoscopic density functional theory (DFT)-based Monte-Carlo approach for studying the phase behaviour of multi-component systems comprised of irreversibly bonded, conventional macromolecules and supramolecular entities was developed.

Perimeter Length and Form Factor of Two-Dimensional Polymer Melts
TL;DR: Using molecular-dynamics simulations, it is shown that the irregular shapes of self-avoiding polymers in two-dimensional melts are characterized by a perimeter length L(N) approximately R(N);{d_{p}} of fractal dimension d_{p}=d-Theta_{2}=5/4 , with Theta=3/4 being a well-known contact exponent.

Scale-free center-of-mass displacement correlations in polymer melts without topological constraints and momentum conservation: a bond-fluctuation model study.
TL;DR: It is argued that the algebraic decay NC(N)(t) ∼ -t(-5/4) for t ≪ T(N) results from an interplay of chain connectivity and melt incompressibility giving rise to the correlated motion of chains and subchains.
