我们猜想了带RR荷的AdS 3× S3 × T4上弦理论的量子谱曲线方程及其CFT 2对偶.我们表明，在大长度制度下，在额外的温和的假设下，QSC再现的渐近贝特Anastomic方程的大规模部门的理论，包括确切的敷料在文献中发现的阶段。QSC的结构与以前已知的AdS 5和AdS 4病例有许多相似之处，但包含一个关键的新特征-分支切割不再是二次的。尽管如此，我们表明，大部分的QSC分析可以适当地推广产生一个自洽系统的方程。虽然进一步的测试是必要的，特别是在大规模部门之外，我们的构造的简单性和自洽性表明了QSC的完整性。
We conjecture the Quantum Spectral Curve equations for string theory on AdS 3× S 3× T 4 with RR charge and its CFT 2 dual. We show that in the large-length regime, under additional mild assumptions, the QSC reproduces the Asymptotic Bethe Ansatz equations for the massive sector of the theory, including the exact dressing phases found in the literature. The structure of the QSC shares many similarities with the previously known AdS 5 and AdS 4 cases, but contains a critical new feature—the branch cuts are no longer quadratic. Nevertheless, we show that much of the QSC analysis can be suitably generalised producing a self-consistent system of equations. While further tests are necessary, particularly outside the massive sector, the simplicity and self-consistency of our construction suggests the completeness of the QSC.
