The Gaiotto-Kim Trace Formula and Line Defects

Sungjoon Kim, Spencer Stubbs

We study the insertion of 4d half-BPS line defects into the trace formula proposed by Gaiotto and Kim, which computes the ellipsoid partition function of the 3d topological quantum…

Three-dimensional TQFTs from Argyres--Douglas theories via the 3d/3d correspondence

Cyril Closset, Adam Keyes, Sungjoon Kim

We study the twisted dimensional reduction of 4d $N = 2$ Argyres--Douglas theories via the 3d/3d correspondence, focussing on $(A_{1}, A_{2 n})$ theories realised as the class…

3d $N =$ 4 rank-0 SCFT from punctured lens space

Sungjoon Kim

{\it Gang-Kim-Stubbs} theory $T_{n}$ --- a pioneering 3d bulk description of $M (2 n + 3, 2)$ Virasoro minimal model as $N = 4$ rank-0 superconformal field theory upon t…
