On near-group centers and super-modular categories (2305.09108v2)

Abstract: The construction and classification of super-modular categories is an ongoing project, of interest in algebra, topology and physics. In a paper, Cho, Kim, Seo and You produced two mysterious families of super-modular data, with no known realization. We show that these data are realized by modifying the Drinfeld centers of near-group fusion categories associated with the groups $\mathbb Z/6$ and $\mathbb Z/2\times \mathbb Z/4$. The methods we develop have wider applications and we describe some of these, with a view towards understanding when near-group centers provide super-modular categories.
