Adding integrable defects to the Boussinesq equation
E. Corrigan, C. Zambon
The purpose of this paper is to extend the store of models able to support integrable defects by investigating the two-dimensional Boussinesq nonlinear wave equation. As has been p…
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…
Aspects of defects in integrable quantum field theory
E. Corrigan
Defects are ubiquitous in nature, for example dislocations, shocks, bores, or impurities of various kinds, and their descriptions are an important part of any physical theory. Howe…
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…
