Purely Transmitting Integrable Defects * )
Some aspects of integrable field theories possessing purely transmitting defects are described. The main example is the sine-Gordon model and several striking features of a classical field theory containing one or more defects are pointed out. Similar features appearing in the associated quantum field theory are also reviewed briefly. 1 Classical picture The context of this topic is two-dimensi...
متن کاملAspects of Purely Transmitting Defects in Integrable Field Theories
Some classical and quantum aspects of integrable defects are reviewed with particular emphasis on the behaviour of solitons in the sine-Gordon model.
متن کاملPurely Transmitting Defect Field Theories
We define an infinite class of integrable theories with a defect which are formulated as chiral defect perturbations of a conformal field theory. Such theories can be interacting in the bulk, and are purely transmitting through the defect. The examples of the sine-Gordon theory and Ising model are worked out in some detail.
متن کاملglN type-I integrable defects
Type-I quantum defects are considered in the context of the glN spin chain. The type-I defects are associated to the generalized harmonic oscillator algebra, and the chosen defect matrix is the one of the vector non-linear Schrödinger (NLS) model. The transmission matrices relevant to this particular type of defects are computed via the Bethe ansatz methodology.
متن کاملIntegrable models with boundaries and defects
Over the past forty years there has been much effort devoted to understanding various aspects of one-dimensional (that is, one space one time, generally denoted by x and t, respectively) field theories both from the classical and quantum points of view and their applications in a variety of contexts. For the most part, attention has been paid to models in the bulk (that is, defined without rest...
