Computer Simulations of Phase Transitions

计算机模拟是除了传统的理论和实验方法之外，获得相互作用凝聚态物质基本信息的另一种方法。将继续发展和改进大规模计算机模拟方法，以研究具有竞争相互作用的系统中的相变，这些方法比更简单的模型更现实，也更难以分析处理。将使用的方法包括蒙特卡罗，蒙特卡罗重整化群，分子动力学；和自旋动力学方法。将考虑的模型预计与磁性材料，立方二元合金，晶体基底上的物理吸附/化学吸附单层和无序介质有关。在低维系统中对线性和非线性激励的研究将投入更多的精力。结果将与理论和/或实验结果进行比较。

Computer simulations are another way of obtaining fundamental information about interacting condensed matter in addition to traditional theoretical and experimental approaches. Development and refinement of large scale computer simulation approaches to study phase transitions in systems with competing interactions, which are both more realistic as well as more difficult to treat analytically than more simplistic models, will continue. Approaches which will be used include Monte Carlo, Monte Carlo Renormalization Group, Molecular Dynamics; and Spin Dynamics methods. Models which will be considered are expected to be relevant to magnetic materials, cubic binary alloys, physisorbed/chemisorbed monolayers on crystalline substrates, and disordered media. Additional effort will be devoted to the study of linear and non-linear excitations in low dimensional systems. The results will be compared with those of theory and/or experiment.
