这项工作提出了在费米子格子场理论中基于流的采样的规范等变结构,使用赝费米子作为费米子行列式的随机估计器。这是最先进的晶格场理论计算中的默认方法,这使得这一发展对于流动模型在QCD等理论中的实际应用至关重要。还概述了通过偶数/奇数预条件和Hasenbusch因式分解等标准技术改进基于流的采样方法的方法。给出了具有费米子性质的二维U(1)和SU(3)规范理论的数值演示。
This work presents gauge-equivariant architectures for flow-based sampling in fermionic lattice field theories using pseudofermions as stochastic estimators for the fermionic determinant. This is the default approach in state-of-the-art lattice field theory calculations, making this development critical to the practical application of flow models to theories such as QCD. Methods by which flow-based sampling approaches can be improved via standard techniques such as even/odd preconditioning and the Hasenbusch factorization are also outlined. Numerical demonstrations in two-dimensional U(1) and SU(3) gauge theories withflavors of fermions are provided.
