ABJ费米气体的定向折叠

Orientifolding of the ABJ Fermi gas

Kazumi Okuyama

摘要:

在费米气体方法中,ABJ理论的巨配分函数在费米子坐标的反映下可以分解为偶、奇两部分。在某些情况下,ABJ巨配分函数的奇偶部分与$O(n)\times USp(n')$理论的奇偶部分相等,因此可以很自然地把ABJ巨配分函数的奇偶投影看作是ABJ费米气体系统的定向折叠。通过系统的WKB分析,我们确定了这种定向折叠ABJ理论巨势微扰部分的系数。我们还找到了前几个“半瞬子”修正的确切形式,这些修正来自费米子坐标反射的扭曲扇区。对于Chern-Simons水平$k=2,4,8$,我们找到了Orientifold ABJ理论的大配分函数的封闭形式表达式,对于$k=2,4$,我们证明了arXiv:1410.7658中所给出的大配分函数之间的函数关系。

英文摘要:

The grand partition functions of ABJ theory can be factorized into even and odd parts under the reflection of fermion coordinate in the Fermi gas approach. In some cases, the even/odd part of ABJ grand partition function is equal to that of $\mathcal{N}=5$ $O(n)\times USp(n')$ theory, hence it is natural to think of the even/odd projection of grand partition function as an orientifolding of ABJ Fermi gas system. By a systematic WKB analysis, we determine the coefficients in the perturbative part of grand potential of such orientifold ABJ theory. We also find the exact form of the first few "half-instanton" corrections coming from the twisted sector of the reflection of fermion coordinate. For the Chern-Simons level $k=2,4,8$ we find closed form expressions of the grand partition functions of orientifold ABJ theory, and for $k=2,4$ we prove the functional relations among the grand partition functions conjectured in arXiv:1410.7658.
