Purely transmitting integrable defects
arXiv:hep-th/0609134 · doi:10.1007/s10582-006-0410-1
Abstract
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.
