Massless renormalization group flow in SU(N)k perturbed conformal field theory
We investigate the infrared properties of SU(N)k conformal field theory perturbed by its adjoint primary field in 1+1 dimensions. The latter field theory is shown to govern the low-energy properties of various SU(N) spin chain problems. In particular, using a mapping onto k-leg SU(N) spin ladder, a...
