Universal shape ratios for polymers grafted at a flat surface
Maria Serena Causo
We consider dilute non-adsorbed polymers grafted at an impenetrable surface and compute several quantities which characterize the polymer shape: the asphericity and the ratios of t…
Crossover phenomena in spin models with medium-range interactions and self-avoiding walks with medium-range jumps
S. Caracciolo, M. S. Causo, A. Pelissetto +2
We study crossover phenomena in a model of self-avoiding walks with medium-range jumps, that corresponds to the limit of an -vector spin system with medium-range intera…
Cut-and-permute algorithm for self-avoiding walks in the presence of surfaces
Maria Serena Causo
We present a dynamic nonlocal hybrid Monte Carlo algorithm consisting of pivot and ``cut-and-permute'' moves. The algorithm is suitable for the study of polymers in semiconfined ge…
Determination of the exponent gamma for SAWs on the two-dimensional Manhattan lattice
Sergio Caracciolo, Maria Serena Causo, Peter Grassberger +1
We present a high-statistics Monte Carlo determination of the exponent gamma for self-avoiding walks on a Manhattan lattice in two dimensions. A conservative estimate is $γ\gtappro…
2-d Self-Avoiding Walks on a Cylinder
Helge Frauenkron, Maria Serena Causo, Peter Grassberger
We present simulations of self-avoiding random walks on 2-d lattices with the topology of an infinitely long cylinder, in the limit where the cylinder circumference L is much small…
Crossover scaling from classical to nonclassical critical behavior
A. Pelissetto, P. Rossi, E. Vicari
We study the crossover between classical and nonclassical critical behaviors. The critical crossover limit is driven by the Ginzburg number G. The corresponding scaling functions a…
High-precision determination of the critical exponent gamma for self-avoiding walks
Sergio Caracciolo, Maria Serena Causo, Andrea Pelissetto
We compute the exponent gamma for self-avoiding walks in three dimensions. We get gamma = 1.1575 +- 0.0006 in agreement with renormalization-group predictions. Earlier Monte Carlo…
