Spontaneous symmetry breaking in the non-linear Schrodinger hierarchy with defect

Vincent Caudrelier, Eric Ragoucy

We introduce and solve the one-dimensional quantum non-linear Schrodinger (NLS) equation for an N-component field defined on the real line with a defect sitting at the origin. The…

The quantum non-linear Schrodinger model with point-like defect

V. Caudrelier, M. Mintchev, E. Ragoucy

We establish a family of point-like impurities which preserve the quantum integrability of the non-linear Schrodinger model in 1+1 space-time dimensions. We briefly describe the co…
