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…
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…
End-to-end distribution function for dilute polymers
Sergio Caracciolo, Maria Serena Causo, Andrea Pelissetto
We study the end-to-end distribution function for dilute polymers. We present a computation to order , , and discuss in detail its asymptotic behaviour for small…
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…
Crossover scaling from classical to non-classical critical behaviour
Sergio Caracciolo, Maria Serena Causo, Andrea Pelissetto +2
Interacting physical systems in the neighborhood of criticality (and massive continuum field theories) can often be characterized by just two physical scales: a (macroscopic) corre…
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…
Monte Carlo results for three-dimensional self-avoiding walks
Sergio Caracciolo, Maria Serena Causo, Andrea Pelissetto
We discuss possible sources of systematic errors in the computation of critical exponents by renormalization-group methods, extrapolations from exact enumerations and Monte Carlo s…
Universality of subleading corrections for self-avoiding walks in presence of one dimensional defects
Sergio Caracciolo, Maria Serena Causo, Andrea Pelissetto
We study three-dimensional self-avoiding walks in presence of a one-dimensional excluded region. We show the appearance of a universal sub-leading exponent which is independent of…
Universality of subleading exponents induced by one dimensional defects the case of self-avoiding walks
Sergio Caracciolo, Maria Serena Causo, Andrea Pelissetto
In this paper we offer some simple and quite general arguments which suggest that the first subleading exponent does not depend on the set of broken symmetries, but only on the…
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…
A class of nonlinear wave equations containing the continuous Toda case
E. Alfinito, M. S. Causo, G. Profilo +1
We consider a nonlinear field equation which can be derived from a binomial lattice as a continuous limit. This equation, containing a perturbative friction-like term and a free pa…
