摘要：
A modified version of the phase-difference model is introduced and diagonalized by means of the algebraic Bethe ansatz. The spectrum is determined for both small and large values of the coupling constant, and the low-lying excitations are shown to exhibit a conformal profile, Applications of the model to quantum optics and growth problems are briefly discussed.
