2D black hole sigma models from an integrable spin chain

Abstract: The staggered six-vertex model is a 1D critical integrable spin chain that exhibits a variety of interesting universal behaviour. This includes a regime where the spectrum of critical exponents contains a continuous component and matches that of the Euclidean version of the 2D black hole non-linear sigma model. In this talk the relation between the scaling limit of the vertex model and the Euclidean/Lorentzian black hole sigma models is discussed. Some new results on the density of states of the continuous spectrum for the Euclidean black hole CFT are presented, which were obtained via an analysis of the lattice system. The talk is largely based on the work 2010.10603.
