dc.descriptionThe one-dimensional quantum sine-Gordon system with a linear spatial modulation is investigated in a special case, $β^{2}$ =4$π$. The model is tranformed into a massive Thirring model and then is exactly diagonalized, the energy spetrum of the model is obtained. Our result clearly demonstrates that cancelling the cosine term without any considering is unadvisable.
