Abstract
A modified version of the phase-difference model is introduced and dia gonalized by means of the algebraic Bethe ansatz. The spectrum is dete rmined for both small and large values of the coupling constant, and t he low-lying excitations are shown to exhibit a conformal profile, App lications of the model to quantum optics and growth problems are brief ly discussed.
