V. Thanh Ngo, D. Tien Hoang, Hung The Diep

摘要:

本文用Ising自旋模型研究了所谓的全阻挫简单立方晶格的相变。我们在这里使用的Monte Carlo方法与平坦的能量直方图Wang-Landau技术,这是非常强大的检测弱一级相变。我们表明,相变显然是一阶的,提供了一个明确的答案25年前提出的问题。

英文摘要:

We show in this paper the results on the phase transition of the so-called fully frustrated simple cubic lattice with the Ising spin model. We use here the Monte Carlo method with the flat energy-histogram Wang-Landau technique which is very powerful to detect weak first-order phase transition. We show that the phase transition is clearly of first order, providing a definite answer to a question raised 25 years ago.
