The quantum nonlinear Schrodinger model with point-like defect

Caudrelier, V., Mintchev, M. & Ragoucy, E. (2004). The quantum nonlinear Schrodinger model with point-like defect. Journal of Physics A: Mathematical and General, 37(30), L367. doi: 10.1088/0305-4470/37/30/L02


We establish a family of point-like impurities which preserve the quantum integrability of the nonlinear Schrödinger model in 1+1 spacetime dimensions. We briefly describe the construction of the exact second quantized solution of this model in terms of an appropriate reflection–transmission algebra. The basic physical properties of the solution, including the spacetime symmetry of the bulk scattering matrix, are also discussed.
