Abstract

A characterization of rational superconformal field theories (SCFTs) on 1+1 dimensions with Ricci-flat Kahler targets was proposed by S. Gukov and C. Vafa in terms of the Hodge structure of the target space. The article [arXiv:2205.10299] refined this idea and extracted a set of necessary conditions for a T4T^4-target N=(1,1) SCFT to be rational; only a partial effort was made, however, to study whether it also constitutes a sufficient condition. It turns out that the set of conditions in [arXiv:2205.10299] is not sufficient, and that it becomes a set of necessary and sufficient conditions by adding one more condition in the case of T4T^4. The Strominger--Yau--Zaslow fibration in the mirror correspondence plays an essential role there. At the end, we also propose a refined version of Gukov--Vafa's idea for general Ricci-flat Kahler target spaces.
