Restricted Quantum Theory of Affine Toda Solitons
J. Underwood, B. Spence
We quantise the reduced theory obtained by substituting the soliton solutions of affine Toda theory into its symplectic form. The semi-classical S-matrix is found to involve the cl…
On the Topological Charges of Affine Toda Solitons
Jonathan Underwood
We provide a proof of a formula conjectured in \cite{OU93} for some coefficients relevant in the principal vertex operator construction of a simply-laced affine algebra $\gh$. Thes…
Affine Toda Solitons and Vertex Operators
D. I. Olive, N. Turok, J. W. R. Underwood
Affine Toda theories with imaginary couplings associate with any simple Lie algebra generalisations of Sine Gordon theory which are likewise integrable and possess solito…
Aspects of Non-Abelian Toda Theories
Jonathan Underwood
We present a definition of the non-abelian generalisations of affine Toda theory related from the outset to vertex operator constructions of the corresponding Kac-Moody algebra $\g…
On a Solitonic Specialisation for the General Solutions of Some Two-Dimensional Completely Integrable Systems
David I. Olive, Mikhail V. Saveliev, Jonathan W. R. Underwood
Following a prescription of \cite{4} for a solitonic specialization of the general solutions to the (abelian) periodic Toda field theories, we discuss a construction of the soliton…
