Аннотация: This paper discusses a new class of spatially localized soliton solutions with bounded energy in the problem of the nonlinear propagation of a light beam along a photorefractive crystal (PRC) with a drift mechanism of nonlinear response. Solitons of this class correspond to stable propagation in the PRC of two or more wave packets (components) that are matched in intensity distribution but incoherent. Their spatial distributions correspond to simultaneous cross-modulation self-locking of its first-and higher-order modes into the common nonlinear waveguide formed by them. It is shown that such multicomponent solitons can be implemented and that they are structurally stable both with respect to collisions and with respect to substantial (more than 10% in intensity) stochastic perturbations of their components as they propagate to distances of the order of several diffraction lengths. The paper discusses the possibility that conjugate polymers, antiferromagnets, and superconductors can contain unusual states corresponding to the stable propagation of two or more mutually incoherent but matched electron wave packets along conjugate chains or along isolated atomic planes.
