Complex sine-Gordon Equation in Coherent Optical Pulse Propagation
Q-Han Park, H. J. Shin
It is shown that the McCall-Hahn theory of self-induced transparency in coherent optical pulse propagation can be identified with the complex sine-Gordon theory in the sharp line l…

Nonabelian sine-Gordon theory and its application to nonlinear optics
Q-Han Park, H. J. Shin
Using a field theory generalization of the spinning top motion, we construct nonabelian generalizations of the sine-Gordon theory according to each symmetric spaces. A Lagrangian f…
