@article{ZinnJustin1997NonlinearIE, title={Nonlinear integral equations for complex affine Toda models associated with simply laced Lie algebras}, author={Paul Zinn-Justin}, journal={Journal of Physics A}, year={1997}, volume={31}, pages={6747-6770} }

A set of coupled nonlinear integral equations (NLIE) is derived for a class of models connected to the quantum group ( simply laced Lie algebra), which are solvable using the Bethe ansatz; these equations describe arbitrary excited states of a system with finite spatial length L. They generalize the simpler NLIE of the sine-Gordon/massive Thirring model to affine Toda field theory with imaginary coupling constant. As an application, the central charge and all the conformal weights of the UV…
