Integrable Defects at Junctions within a Network
E. Corrigan, C. Zambon
The purpose of this article is to explore the properties of integrable, purely transmitting, defects placed at the junctions of several one-dimensional domains within a network. Th…
Infinite dimension reflection matrices in the sine-Gordon model with a boundary
E. Corrigan, C. Zambon
Using the sine-Gordon model as the prime example an alternative approach to integrable boundary conditions for a theory restricted to a half-line is proposed. The main idea is to e…
A transmission matrix for a fused pair of integrable defects in the sine-Gordon model
E. Corrigan, C. Zambon
Within the quantum sine-Gordon model a transmission matrix describing the scattering of a soliton with a fused pair of integrable defects is proposed. The result is consistent with…
A new class of integrable defects
E. Corrigan, C. Zambon
An alternative Lagrangian definition of an integrable defect is provided and analyzed. The new approach is sufficiently broad to allow a description of defects within the Tzitzeica…
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…
