Nonlinear propagation of vector extremely short pulses in a medium of symmetric and asymmetric molecules

摘要: The nonlinear propagation of extremely short electromagnetic pulses in a medium symmetric and asymmetric molecules placed static magnetic electric fields is theoretically studied. Asymmetric differ that they have nonzero permanent dipole moments stationary quantum states. A system wave equations derived for the ordinary extraordinary components pulses. It shown this can be reduced some cases to coupled Ostrovsky equation intagrable by method an inverse scattering transformation, including vector version Ostrovsky–Vakhnenko equation. Different types solutions are considered. Only representing superposition periodic single-valued, whereas soliton breather multivalued.
