Normalization 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...

Reflection Amplitudes of Boundary Toda Theories and Thermodynamic Bethe Ansatz

We study the ultraviolet asymptotics in An affine Toda theories with integrable boundary actions. The reflection amplitudes of non-affine Toda theories in the presence of conformal boundary actions have been obtained from the quantum mechanical reflections of the wave functional in the Weyl chamber and used for the quantization conditions and ground-state energies. We compare these results with...

Defects in affine Toda field theories

In this talk some classical and quantum aspects concerning a special kind of integrable defect called a jump-defect will be reviewed. 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. 1 E-mail: [email protected]

Quantum group symmetry in sine-Gordon and affine Toda field theories on the half-line

We consider the sine-Gordon and affine Toda field theories on the half-line with classically integrable boundary conditions, and show that in the quantum theory a remnant survives of the bulk quantized affine algebra symmetry generated by nonlocal charges. The paper also develops a general framework for obtaining solutions of the reflection equation by solving an intertwining property for repre...
