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…
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…
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…
On the 4d/3d/2d view of the SCFT/VOA correspondence
Mykola Dedushenko
We start with the SCFT/VOA correspondence formulated in the Omega-background approach, and connect it to the boundary VOA in 3d theories and chiral algebras of 2d $…
Interfaces and Quantum Algebras, II: Cigar Partition Function
Mykola Dedushenko, Nikita Nekrasov
The supersymmetric cigar (half-)index or cigar partition function of 3d gauge theories contains a wealth of information. Physically, it captures the spectrum of BPS…
Interval reduction and (super)symmetry
Mykola Dedushenko, Mikhail Litvinov
We study three-dimensional quantum field theories on the interval with symmetry-preserving boundary conditions. The physics and symmetries of the effective 2D theory in the IR are…
