International Conference on Statistical Physics
作者: Okabe, Y Tomita, Y Yamaguchi, C Tokyo Metropolitan Univ Dept Phys Hachioji Tokyo 1920397 Japan
We explain the idea of the probability-changing cluster (PCC) algorithm, which is an extended version of the Swendsen-Wang algorithm. With this algorithm, we can tune the critical point automatically. We show the effe... 详细信息

Critical dynamics of two-replica cluster algorithms
收藏 引用
INTERNATIONAL JOURNAL OF MODERN PHYSICS C 2001年 第2期12卷 257-271页
作者: Li, XN Machta, J Univ Massachusetts Dept Phys Amherst MA 01003 USA
The dynamic critical behavior of the two-replica cluster algorithm is studied. Several versions of the algorithm are applied to the two-dimensional, square lattice Ising model with a staggered field. The dynamic expon... 详细信息

JOURNAL OF CHEMICAL PHYSICS 2001年 第13期114卷 5853-5862页
作者: Dillmann, O Janke, W Müller, M Binder, K Univ Mainz Inst Phys D-55099 Mainz Germany Inst Theoret Phys D-04109 Leipzig Germany
Extending the Swendsen-Wang cluster algorithm to include both bulk (H) and surface fields (H-1) in LxLxD Ising films of thickness D and two free LxL surfaces, a Monte Carlo study of the capillary condensation critical... 详细信息

NUCLEAR PHYSICS B 2000年 第1-2期583卷 331-346页
作者: Cox, J Holland, K MIT Ctr Theoret Phys Nucl Sci Lab Dept Phys Cambridge MA 02139 USA Univ Bern Inst Theoret Phys CH-3012 Bern Switzerland
The recently developed meron-cluster algorithm completely solves the exponentially difficult sign problem for a number of models previously inaccessible to numerical simulation. We use this algorithm in a high-precisi... 详细信息

Universal amplitude ratios in the critical two-dimensional Ising model on a torus
收藏 引用
JOURNAL OF STATISTICAL PHYSICS 2000年 第3-4期98卷 551-588页
作者: Salas, J Sokal, AD Univ Zaragoza Fac Ciencias Dept Fis Teor Zaragoza 50009 Spain Univ Zaragoza Fac Ciencias Dept Fis Mat Condensada Zaragoza 50009 Spain NYU Dept Phys New York NY 10003 USA
Using results from conformal field theory, we compute several universal amplitude ratios for the two-dimensional Ising model at criticality on a symmetric torus. These include the correlation-length ratio x* = lim(L--... 详细信息

cluster Monte Carlo study of multicomponent fluids of the Stillinger-Helfand and Widom-Rowlinson type
收藏 引用
Physical Review E 2000年 第2期62卷 2226-2226页
作者: Rongfeng Sun Harvey Gould J. Machta L. W. Chayes Department of Mathematics University of California Los Angeles California 90095-1555
Phase transitions of fluid mixtures of the type introduced by Stillinger and Helfand are studied using a continuum version of the invaded cluster algorithm. Particles of the same species do not interact, but particles... 详细信息

收藏 引用
JOURNAL OF COMPUTATIONAL AND GRAPHICAL STATISTICS 1999年 第2期8卷 353-372页
作者: Cai, HY Univ Missouri Dept Math & Comp Sci St Louis MO 63121 USA
In this article, Swendsen-Wang-Wolff algorithms are extended to simulate spatial point processes with symmetric and stationary interactions. Convergence of these algorithms is considered. Some further generalizations ... 详细信息

INTERNATIONAL JOURNAL OF MODERN PHYSICS C 1999年 第8期10卷 1427-1432页
作者: Machta, J Univ Massachusetts Dept Phys & Astron Amherst MA 01002 USA
Efficient cluster algorithms for Ising systems with fields are described. cluster are grown between two replicas of the system in the same field. As is the case for other successful cluster approaches, the critical po... 详细信息

Study of phase separation in a first-order phase transition:: Nucleation versus spinodal decomposition
收藏 引用
INTERNATIONAL JOURNAL OF MODERN PHYSICS C 1999年 第7期10卷 1261-1269页
作者: Arkin, H Çelik, T Berg, BA Meyer-Ortmanns, H Hacettepe Univ Dept Phys Ankara Turkey Florida State Univ Dept Phys Tallahassee FL 32306 USA Univ Gesamthsch Wuppertal Fachbereich Phys Wuppertal Germany
Studies of dynamical properties of first-order phase transition for a scalar field theory indicate that the phase conversion mechanism itself depends on the strength of the first-order transition: if the transition is... 详细信息
