Comments on defects in the a_r Toda field theories
E. Corrigan, C. Zambon
A simple, basic, argument is given, based solely on energy-momentum considerations to recover conditions under which a_r affine or conformal Toda field theories can support defects…
On purely transmitting defects in affine Toda field theory
E. Corrigan, C. Zambon
Affine Toda field theories with a purely transmitting integrable defect are considered and the model based on a_2 is analysed in detail. After providing a complete characterization…
Jump-defects in the nonlinear Schrodinger model and other non-relativistic field theories
E. Corrigan, C. Zambon
Recent work on purely transmitting 'jump-defects' in the sine-Gordon model and other relativistic field theories is extended to non-relativistic models. In all the cases investigat…
Affine Toda field theories with defects
P. Bowcock, E. Corrigan, C. Zambon
A Lagrangian approach is proposed and developed to study defects within affine Toda field theories. In particular, a suitable Lax pair is constructed together with examples of cons…
