Instability of Solitons in imaginary coupling affine Toda Field Theory
Affine Toda field theory with a pure imaginary coupling constant is a nonhermitian theory. Therefore the solutions of the equation of motion are complex. However, in 1 + 1 dimensions it has many soliton solutions with remarkable properties, such as real total energy/momentum and mass. Several authors calculated quantum mass corrections of the solitons by claiming these solitons are stable. We s...
متن کاملAffine Toda Field Theory
We present one loop boundary reflection matrix for d (1) 4 Toda field theory defined on a half line with the Neumann boundary condition. This result demonstrates a nontrivial cancellation of non-meromorphic terms which are present when the model has a particle spectrum with more than one mass. Using this result, we determine uniquely the exact boundary reflection matrix which turns out to be ‘n...
متن کاملToda field theory
TheR-matrix of the Uq ( d (3) 4 ) algebra is constructed in the 8-dimensional fundamental representation. Using this result, an exact S-matrix is conjectured for the imaginary coupled g (1) 2 affine Toda field theory, the structure of which is found to be very similar to the previously investigated S-matrix of d (3) 4 Toda theory. It is shown that this Smatrix is consistent with the results for...
متن کاملQuantum Affine Symmetry and Scattering Amplitudes of the Imaginary Coupled d ( 3 ) 4 Affine Toda Field Theory
An exact S-matrix is conjectured for the imaginary coupled d (3) 4 affine Toda field theory, using the U q (g (1) 2) symmetry. It is shown that this S-matrix is consistent with the results for the case of real coupling using the breather-particle correspondence. For q a root of unity it is argued that the theory can be restricted to yield Φ(11|14) perturbations of W A 2 minimal models and the r...
متن کاملAffine Toda field theory from tree unitarity
Elasticity property ( i.e. no-particle creation ) is used in the tree level scattering of scalar particles in 1+1 dimensions to construct affine Toda field theory(ATFT) associated with the root systems of groups a (2) 2 and c (1) 2 . A general prescription is given for constructing ATFT (associated with rank two root systems) with two self conjugate scalar fields. It is conjectured that the sam...
