Bridging 4D QFTs and 2D VOAs via 3D high-temperature EFTs
Arash Arabi Ardehali, Mykola Dedushenko, Dongmin Gang +1
The high-temperature limit of the superconformal index, especially on higher sheets, often captures useful universal information about a theory. In 4d superconforma…

Coulomb Branches of Noncotangent Type: a Physics Perspective
Mykola Dedushenko, Daniel Resnick
We study the Coulomb-branch sector of 3D gauge theories with half-hypermultiplets in general pseudoreal representations ("noncotangent" theories). This…

Ising BCFT from Fuzzy Hemisphere
Mykola Dedushenko
We extend the recently introduced fuzzy sphere technique for the 3d Ising CFT to the case of boundary CFT (BCFT) using the fuzzy hemisphere. This allows to study conformal boundary…
