New Integrable field theories from extreme twisting of N=4 SYM and ABJM: correlation functions, amplitudes and logarithmic CFTs

Description
I will explain the construction of a new class of integrable field theories in higher dimensions arising from a double scaling limit of integrable deformations of known superconformal field theories that combine weak coupling with strong twist. The resulting theories possess an extremely simple perturbation theory shedding light on the origins of integrability. At the same time, all integrability tools can still be used for the computation of observables such as correlation functions and amplitudes.
I will also mention some unusual features like the emergence of logarithmic CFT sectors and manifestly Yangian invariant amplitudes.
