The phase diagram of the one-dimensional quantum sine-Gordon system ($Î²^{2}=4Ï)$ with a linear spatial modulation

arXiv:cond-mat/0104161

Abstract

The one-dimensional quantum sine-Gordon system with a linear spatial modulation is investigated in a special case, $Î²^{2}$ =4 $I ¨ $ . 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.
