In particular, recent results obtained in an attempt to incorporate this defect in the affine Toda field theories, in addition to the sine-Gordon model, will be presented.Contribution to the proceedings of the International Workshop RAQIS'07, Recent Advances in Quantum Integrable Systems, 11-14 Semptember 2007High Energy Physics - Theorytext
