CPT Student Seminar: Defects in affine Toda field theories

Presented by Rebecca Bristow, Durham University

23 November 2015 17:00 in OC218

It is possible for some classical 1+1-dimensional integrable field theories to accommodate discontinuities in the fields and yet remain integrable, with the fields on either side of the defect related by some set of defect conditions. In this talk, momentum conserving defects in the ATFTs based on the A series of Lie algebras and in the Tzitzeica model are reviewed, and the fact that the defect conditions give a Backlund transformation for the bulk theory is noted. A more general form of the defect is then considered, which is momentum conserving for ATFTs based on the B, C and D series of Lie algebras.
