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…
Defects in affine Toda field theories
Cristina Zambon
In this talk some classical and quantum aspects concerning a special kind of integrable defect - called a jump-defect - will be reviewed. In particular, recent results obtained in…
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…
Aspects of sine-Gordon solitons, defects and gates
E. Corrigan, C. Zambon
It was recently noted how the classical sine-Gordon theory can support discontinuities, or `defects', and yet maintain integrability by preserving sufficiently many conservation la…
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…
Classically integrable field theories with defects
P. Bowcock, E. Corrigan, C. Zambon
Some ideas and remarks are presented concerning a possible Lagrangian approach to the study of internal boundary conditions relating integrable fields at the junction of two domain…
