Abstract: 

In this talk we will consider the spectrum of anomalous dimensions in N=4 super-Yang-Mills and related theories. We will first discuss the presence of quantum chaos at finite N and how the perturbative spectrum is well described by GOE random matrix theory. We will then describe how the integrability of the planar-limit can be used to rewrite the computation of 1/N corrections to the one-loop anomalous dimensions in terms of scalar products of off-shell Bethe states or, alternatively, hexagon-like functions.
