Orbifold groupoids
Davide Gaiotto, Justin Kulp
We review the properties of orbifold operations on two-dimensional quantum field theories, either bosonic or fermionic, and describe the "Orbifold groupoids" which control the comp…

Two More Fermionic Minimal Models
Justin Kulp
In this short note, we comment on the existence of two more fermionic unitary minimal models not included in recent work by Hsieh, Nakayama, and Tachikawa. These theories are obtai…
