新方法使用归一化流对 SU(N) 格点规范理论进行采样

作者 PulseAugur 编辑部 · [1 个来源] · 2026-10-06 21:42

研究人员开发了一种使用归一化流在二维格点上采样 SU(N) 规范理论的新颖方法。该方法通过将作用重新表述为全纯变量来解决在格点规范理论中将采样到的劈形图映射到连接变量的挑战。该方法涉及一个条件采样问题，其中劈形图是独立采样的，权重由角点变量的群换位子决定。该技术在 SU(2) 和 SU(3) 理论的各种格点尺寸和耦合上的测试中显示出高接受率和中等有效样本量。 AI

影响引入了归一化流在复杂物理模拟中的新颖应用，有可能推进理论物理学中的计算方法。

通过全纯和角重加权在二维格点上对SU(N)规范理论进行采样

In the Wilson formulation of lattice gauge theory, the fundamental degrees of freedom are group-valued link variables, while the action is a sum over the trace of the plaquettes, the smallest Wilson loops. For generative sampling methods such as normalizing flows, this poses a ch…
