Polymer collapse and crystallization in bond fluctuation models
Peter Grassberger
While the -collapse of single long polymers in bad solvents is usually a continuous (tri-critical) phase transition, there are exceptions where it is preempted by a discontinuou…
A review of Monte Carlo simulations of polymers with PERM
Hsiao-Ping Hsu, Peter Grassberger
In this review, we describe applications of the pruned-enriched Rosenbluth method (PERM), a sequential Monte Carlo algorithm with resampling, to various problems in polymer physics…
Polymers grafted to porous membranes
Hsiao-Ping Hsu, Peter Grassberger
We study a single flexible chain molecule grafted to a membrane which has pores of size slightly larger than the monomer size. On both sides of the membrane there is the same solve…
Collapsing lattice animals and lattice trees in two dimensions
Hsiao-Ping Hsu, Peter Grassberger
We present high statistics simulations of weighted lattice bond animals and lattice trees on the square lattice, with fugacities for each non-bonded contact and for each bond betwe…
The coil-globule transition of confined polymers
Hsiao-Ping Hsu, Peter Grassberger
We study long polymer chains in a poor solvent, confined to the space between two parallel hard walls. The walls are energetically neutral and pose only a geometric constraint whic…
Simulations of grafted polymers in a good solvent
Peter Grassberger
We present improved simulations of three-dimensional self avoiding walks with one end attached to an impenetrable surface on the simple cubic lattice. This surface can either be a-…
Monte Carlo Protein Folding: Simulations of Met-Enkephalin with Solvent-Accessible Area Parameterizations
Hsiao-Ping Hsu, Bernd A. Berg, Peter Grassberger
Treating realistically the ambient water is one of the main difficulties in applying Monte Carlo methods to protein folding. The solvent-accessible area method, a popular method fo…
Effective interactions between star polymers
Hsiao-Ping Hsu, Peter Grassberger
We study numerically the effective pair potential between star polymers with equal arm lengths and equal number of arms. The simulations were done for the soft core Domb-Joyce…
Scaling of Star Polymers with one to 80 Arms
Hsiao-Ping Hsu, Walter Nadler, Peter Grassberger
We present large statistics simulations of 3-dimensional star polymers with up to arms, and with up to 4000 monomers per arm for small values of . They were done for the…
Polymers Confined between Two Parallel Plane Walls
Hsiao-Ping Hsu, Peter Grassberger
Single three dimensional polymers confined to a slab, i.e. to the region between two parallel plane walls, are studied by Monte Carlo simulations. They are described by -step wa…
2-Dimensional Polymers Confined in a Strip
Hsiao-Ping Hsu, Peter Grassberger
Single two dimensional polymers confined to a strip are studied by Monte Carlo simulations. They are described by N-step self-avoiding random walks on a square lattice between two…
Exactness of the Annealed and the Replica Symmetric Approximations for Random Heteropolymers
Ugo Bastolla, Peter Grassberger
We study a heteropolymer model with random contact interactions introduced some time ago as a simplified model for proteins. The model consists of self-avoiding walks on the simple…
A Simple Model for the DNA Denaturation Transition
Maria Serena Causo, Barbara Coluzzi, Peter Grassberger
We study pairs of interacting self-avoiding walks on the 3d simple cubic lattice. They have a common origin and are allowed to overlap only at the same monomer position along the c…
Critical Unmixing of Polymer Solutions
H. Frauenkron, P. Grassberger, HLRZ Juelich +1
We present Monte Carlo simulations of semidilute solutions of long self-attracting chain polymers near their Ising type critical point. The polymers are modeled as monodisperse sel…
