Dyonic integrable models
Abstract
A class of nonabelian affine Toda models arising from the axial gauged twoloop WZW model is presented. Their zero curvature representation is constructed in terms of a graded KacMoody algebra. It is shown that the discrete multivacua structure of the potential together with nonabelian nature of the zero grade subalgebra allows soliton solutions with nontrivial electric and topological charges. The dressing transformation is employed to explicitly construct one and two soliton solutions and their bound states in terms of the tau functions. A discussion of the classical spectra of such solutions and the time delays are given in detail.
