雷蒙部门的经验教训

Lessons from the Ramond sector

Nathan Benjamin, Ying-Hsuan Lin

摘要:

我们重新审视了(1+1)$d$费米子共形场论中环面配分函数的一致性,将传统的模不变性/协变性成分与玻色化/费米子化对偶的现代理解相结合。通过简单地检查经常被忽视的雷蒙部门,可以吸取各种教训。对于bootstrap文献中的几个极值/扭结模函数,我们可以排除或识别潜在的理论。我们还重新访问的${\cal N} = 1$ Maloney-Witten配分函数计算的频谱在Ramond部门,并进一步扩展到包括种子Ramond字符的模和。最后,我们进行了完整的${\cal N} = 1$ RNS模块化引导,并获得了新的普遍结果的存在相关的变形保持不同数量的超对称性。

英文摘要:

We revisit the consistency of torus partition functions in (1+1)$d$ fermionic conformal field theories, combining traditional ingredients of modular invariance/covariance with a modernized understanding of bosonization/fermionization dualities. Various lessons can be learned by simply examining the oft-ignored Ramond sector. For several extremal/kinky modular functions in the bootstrap literature, we can either rule out or identify the underlying theory. We also revisit the ${\cal N} = 1$ Maloney-Witten partition function by calculating the spectrum in the Ramond sector, and further extending it to include the modular sum of seed Ramond characters. Finally, we perform the full ${\cal N} = 1$ RNS modular bootstrap and obtain new universal results on the existence of relevant deformations preserving different amounts of supersymmetry.
