论文摘要
非零密度QCD的晶格模拟引入了所谓的符号问题（复杂或负概率），从而使重要性采样方法无效。为了绕过这一点，我们使用复杂的langevin方程（CLE）来测量边界项，然后将这些结果与从重新持续的结果进行比较，从而证实了先前研究的期望。我们还使用具有动态稳定的CLE在模拟中调查了边界项，并将其比较，与重新处理计算的结果。
Lattice simulations of non-zero density QCD introduce the so-called sign problem (complex or negative probabilities), which invalidates importance sampling methods. To circumvent this, we use the Complex Langevin Equation (CLE), to measure the boundary terms and then compare these results with the ones gotten from reweighting, confirming the expectations from previous studies. We also investigate boundary terms in simulations using CLE with dynamic stabilization and compare this, to results calculated with reweighting.
