Author: Ofer Biham

Blöte, Henk W.J.
Title: Potts models with long-ranged interactions
Author: Henk W.J. Blöte
Affiliation: Lorentz Institute, Leiden University, Netherlands
Abstract:
Simulations of models with long-range interactions by means of cluster methods can, in many cases, be arranged such that the number of operations needed to update one particle becomes independent on the range of the interactions. This makes it possible to perform very efficient simulations of long-range Potts models.

Martín-Mayor, Víctor
Title: Monte Carlo simulations of (quasi) constrained ensembles
Author: Víctor Martín-Mayor
Affiliation: Universidad Complutense de Madrid, Spain
Abstract:
The standard Monte Carlo simulation of systems displaying metastability is very inefficient, (think of first-order phase transitions, spin glasses, structural glasses, lattice polymers, etc.). One may use constrained statistical ensembles in order to guide the simulation inside those rare but crucial regions where it does not want to get into.

Title: Hybrid Reverse Monte Carlo Modelling of Disordered Materials
Author: G. Opletal, S. Russo and I. Snook
Affiliation: Applied Physics, School of Applied Science, RMIT University, Melbourne, Australia
Abstract:
In the construction of models of amorphous materials, the Reverse Monte Carlo modelling methodology, which traditionally only fits experimental diffraction data, suffers from a lack of uniqueness. For a particular data set, many unphysical atomic configurations are possible.

Per, Manolo
Title: Efficient calculation of unbiased estimates in diffusion quantum Monte Carlo
Author: Manolo Per
Affiliation: Applied Physics, School of Applied Science, RMIT University, Melbourne, Australia
Abstract:
The diffusion quantum Monte Carlo (DQMC) method is a powerful and relatively straightforward technique for calculating quantum mechanical properties of a wide variety of systems at zero temperature. However, expectation values of operators which do not commute with the Hamiltonian exhibit large variances and a systematic bias.

Title: PERM and all that - a comparison of growth algorithms
Author: Thomas Prellberg
Affiliation: Queen Mary, University of London
Abstract:
Over the last few years, there have been a variety of growth-like algorithms, such as PERM, IGW, GARM, and GAS. Some of these have been coupled with flat-histogram techniques, resulting in multicanonical PERM, flatPERM, flatIGW.
In this talk we will describe these various algorithms, point out their differences, and discuss their respective strengths.

Title: Dynamic critical behavior of the Wang-Swendsen-Kotecky algorithm for two-dimensional Potts antiferromagnets
Author: Jesus Salas
Affiliation: Universidad Carlos III de Madrid, Spain
Abstract:
The phase diagram of the antiferromagnetic q-state Potts model is not universal: it depends, in addition to the number of states q and the dimensionality of the lattice, on the lattice structure. Therefore, one has to study this model on a case-by-case basis.

Sasaki, Munetaka
Title: Stochastic Cutoff Method for Long-Range Interacting Systems
Authors: Munetaka Sasaki and Kazuya Watanabe
Affiliation: Tohoku University, Japan
Abstract:
In this work, we present an efficient Monte-Carlo (MC) method called stochastic cutoff method for long-range interacting systems. This method enables us to reduce the computational time per MC step from O(N2) to O(N) (or O(N log N)) without any approximation, where N is the number of elements. The efficiency of the method is demonstrated by applying it to magnetic dipolar systems.

Seoane, Beatriz
Title: Effective potential study of hard-spheres crystallization
Author: Beatriz Seoane
Affiliation: Universidad Complutense de Madrid, Spain
Abstract:
We use tethered Monte Carlo to study the fluid-solid phase transition in hard spheres at constant pressure. Tethered Monte Carlo features directly the effective potential by simulation of constrained statistical ensembles. In order to avoid metastabilities, we have found it crucial to constraint the values of two crystalline order parameters, namely Q_6 and C.
