| We investigate numerically by a conservative difference scheme in complex arithmetic the head-on and taking over collision dynamics of the solitary waves as solutions of linearly Coupled Nonlinear Schrodinger Equations for various initial phases. The initial conditions are superposition of two one-soliton solutions with general polarization. The quasi-particle behavior of propagating and interacting solutions in conditions of rotational polarization is examined. We find that the total mass, pseudomomentum and energy are conserved while the local masses, individual and total polarization depend strongly on the initial phase difference. We also find out that the polarization angle of the quasi particles can change independently of the interaction.
The investigation is partially supported by the Science Fund of Ministry of Education, Science and Youth of Republic Bulgaria under grant DDVU02/71. |
