- Abstract
The critical behaviour of an integrable model of a spin- 1/2 chain with nearest-neighbour XXZ interaction and a competing three-spin interaction involving nearest and next-nearest neighbours is studied. The phase diagram at zero temperature is obtained. Methods from conformal field theory are used to compute the asymptotics of the spin-spin correlation functions.
