Abstract
Dynamics of (1+1)D spatial solitons in photorefractive medium with drift and diffusion nonlinearity is investigated. Propagation of solitons is analyzed theoretically by means of effective-particle approach method. The explicit formula of acceleration of soltion is derived. Analytical results show that the solitons evolve with a constant acceleration along a parabolic trajectory. The acceleration is determined by the input soliton and the diffusion nonlinearity. We also simulate the propagation of solitons numerically and excellent agreements are obtained between the theoretical and numerical results.
