最近的数值结果表明，在临界三维伊辛模型中存在共形不变的扭曲缺陷。在本说明中，我们表明，这一事实是支持的两个展开和共形引导计算。我们发现我们的结果与数值数据吻合得很好。我们还提出了新的预测运营商的尺寸和OPE系数的自举方法。在这个过程中，我们推导出一维共形场论和共形线缺陷的普遍边界。
Recent numerical results point to the existence of a conformally invariant twist defect in the critical 3d Ising model. In this note we show that this fact is supported by both epsilon expansion and conformal bootstrap calculations. We find that our results are in good agreement with the numerical data. We also make new predictions for operator dimensions and OPE coefficients from the bootstrap approach. In the process we derive universal bounds on one-dimensional conformal field theories and conformal line defects.
