论文摘要
在采用诸如Monte-Carlo技术之类的计算昂贵方法之前，平均场近似通常用于探索经典自旋模型中相变的定性行为。我们实施了“晶格位点分辨”的平均场自旋模型，该模型允许在复杂磁性域的相之间有效模拟相变（例如磁性螺旋螺旋，天空或带有倾斜的旋转状态）。该框架可作为一种互补方法，用于预审查复杂磁体中相图的定性特征。
Mean-field approximation is often used to explore the qualitative behaviour of phase transitions in classical spin models before employing computationally costly methods such as the Monte-Carlo techniques. We implement a 'lattice site-resolved' mean-field spin model that allows efficient simulation of phase transitions between phases of complex magnetic domains, such as magnetic helices, skyrmions, or states with canted spins. The framework is useful as a complementary approach for pre-screening the qualitative features of phase diagrams in complex magnets.
