Systematic approach to correlators in deformed CFTs
Song He, Yuan Sun, Jiashi Yin
We investigate higher-order corrections to correlators in a general CFT (conformal field theory) with the double-trace deformation. Standard perturbation theory proves i…

Deformation: Introduction and Some Recent Advances
Song He, Yi Li, Hao Ouyang +1
This review explores recent advances in the theory of deformation, an irrelevant yet solvable deformation of quantum field theories defined via the quadratic form of the…
