Background field boundary conditions for affine Toda field theories
arXiv:hep-th/9510071 · doi:10.1016/0550-3213(96)00050-8
Abstract
Classical integrability is investigated for affine Toda field theories in the presence of a constant background tensor field. This leads to a further set of discrete possibilities for integrable boundary conditions depending upon the time-derivative of the fields at the boundary but containing no free parameters other than the bulk coupling constant.
