标题： Scaling tests with dynamical overlap and rooted staggered fermions

摘要： 我们对具有完整重叠和根化阶梯行列式的1味施温格模型进行了尺度分析。在后一种情况下，标量凝聚的手征极限和连续极限不相容，而对于重叠费米子则相容。对于拓扑易变性，建议了一个普遍的连续极限，如同分区函数和勒特维勒-斯米尔加求和规则一样。在重夸克力中，即使在有限耦合下也看不到差异。最后，将完整的重叠与根化阶梯行列式直接比较，结果表明它们的比值在考虑$O(a^2)$效应的情况下是恒定的。 显示英文摘要

摘要： We present a scaling analysis in the 1-flavor Schwinger model with the full overlap and the rooted staggered determinant. In the latter case the chiral and continuum limit of the scalar condensate do not commute, while for overlap fermions they do. For the topological susceptibility a universal continuum limit is suggested, as is for the partition function and the Leutwyler-Smilga sum rule. In the heavy-quark force no difference is visible even at finite coupling. Finally, a direct comparison between the complete overlap and the rooted staggered determinant yields evidence that their ratio is constant up to $O(a^2)$ effects.
