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 کاملTransmitting and decoding facial expressions.
This article examines the human face as a transmitter of expression signals and the brain as a decoder of these expression signals. If the face has evolved to optimize transmission of such signals, the basic facial expressions should have minimal overlap in their information. If the brain has evolved to optimize categorization of expressions, it should be efficient with the information availabl...
متن کاملInformation processing in transmitting recombination
The validity of a general template for transmitting recombination operators is established, and a sufficient condition to ensure the independence of the pieces of information manipulated in the process from the particulars of the operator is given.
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.
