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 the semi-dynamical reflection equation: solutions and structure matrices
J. Avan, C. Zambon
Explicit solutions of the non-constant semi-dynamical reflection equation are constructed, together with suitable parametrizations of their structure matrices. Considering the semi…
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…
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…
