Toda field theories
نویسنده
چکیده
A simple, basic, argument is given, based solely on energy-momentum considerations to recover conditions under which ar affine or conformal Toda field theories can support defects of integrable type. Associated triangle relations are solved to provide expressions for transmission matrices that generalize previously known examples calculated for the sine-Gordon model and the a2 affine Toda model.

Point Symmetries of Generalized Toda Field Theories II Applications of the Symmetries
The Lie symmetries of a large class of generalized Toda field theories are studied and used to perform symmetry reduction. Reductions lead to generalized Toda lattices on one hand, to periodic systems on the other. Boundary conditions are introduced to reduce theories on an infinite lattice to those on semi-infinite, or finite ones.
متن کاملWave function renormalization constants and one - particle form factors in D ( 1 ) l Toda field theories
We apply the method of angular quantization to calculation of the wave function renormalization constants in D (1) l affine Toda quantum field theories. A general formula for the wave function renormalization constants in ADE Toda field theories is proposed. We also calculate all one-particle form factors and some of the two-particle form factors of an exponential field. August, 1998 ∗ e-mail a...
متن کاملToda Theories as Contractions of Affine Toda Theories
Using a contraction procedure, we obtain Toda theories and their structures, from affine Toda theories and their corresponding structures. By structures, we mean the equation of motion, the classical Lax pair, the boundary term for half line theories, and the quantum transfer matrix. The Lax pair and the transfer matrix so obtained, depend nontrivially on the spectral parameter. A Toda field th...
متن کاملNormalization Factors, Reflection Amplitudes and Integrable Systems
We calculate normalization factors and reflection amplitudes in the Winvariant conformal quantum field theories. Using these CFT data we derive vacuum expectation values of exponential fields in affine Toda theories and related perturbed conformal field theories. We apply these results to evaluate explicitly the expectation values of order parameters in the field theories associated with statis...
متن کاملAffine Toda field theories related to Coxeter groups of non-crystallographic type
We propose affine Toda field theories related to the non-crystallographic Coxeter groups H2, H3 and H4. The classical mass spectrum, the classical three-point couplings and the one-loop corrections to the mass renormalisation are determined. The construction is carried out by means of a reduction procedure from crystallographic to non-crystallographic Coxeter groups. The embedding structure exp...
