Integrated correlators from integrability: Maldacena-Wilson line in $\mathcal{N}=4$ SYM

: We present a systematic method for the derivation of a relation which connects the correlation function of operators on the straight Maldacena-Wilson line with the integrability data for the cusp

The cusp anomalous dimension at three loops and beyond

We derive an analytic formula at three loops for the cusp anomalous dimension Γcusp(ϕ) in $ \mathcal{N} = {4} $ super Yang-Mills. This is done by exploiting the relation of the latter to the Regge

Quantum fishchain in AdS5

In our previous paper we derived the holographic dual of the planar fishnet CFT in four dimensions. The dual model becomes classical in the strongly coupled regime of the CFT and takes the form of an

Derivation of the Holographic Dual of a Planar Conformal Field Theory in 4D.

The first-principles derivation of a weak-strong duality between the fishnet theory in four dimensions and a discretized stringlike model living in five dimensions is presented and it is demonstrated explicitly the classical integrability of the model.
