    Specific Features of the Self-Action Dynamics of Wave Packets with Initially Normal Group-Velocity Dispersion in Nonlinear Lattices

    Specific features of the self-action of wave fields are studied in the framework of a discrete nonlinear Schrödinger equation (DNSE). It is shown analytically and numerically that the dynamics of wave packets ...

    Spatiotemporal Regimes in the Kuramoto–Battogtokh System of Nonidentical Oscillators

    We consider the spatiotemporal states of an ensemble of nonlocally coupled nonidentical phase oscillators, which correspond to different regimes of the long-term evolution of such a system. We have obtained ho...

    Peculiarities of the Self-Action of Inclined Wave Beams Incident on a Discrete System of Optical Fibers

    Based on a discrete nonlinear Schrödinger equation (DNSE), we studied analytically and numerically the peculiarities of the self-action of one-dimensional quasi-optic wave beams injected into a spatially inhom...

    Breathing chimera in a system of phase oscillators

    Chimera states consisting of synchronous and asynchronous domains in a medium of nonlinearly coupled phase oscillators have been considered. Stationary inhomogeneous solutions of the Ott–Antonsen equation for ...

    Scattering of a vortex pair by a single quantum vortex in a Bose–Einstein condensate

    We analyze the scattering of vortex pairs (the particular case of 2D dark solitons) by a single quantum vortex in a Bose–Einstein condensate with repulsive interaction between atoms. For this purpose, an asymp...

    Propagation and annihilation of vortex pairs in a smoothly inhomogeneous Bose-Einstein condensate

    An asymptotic theory has been developed to describe the propagation and annihilation of vortex pairs in a smoothly inhomogeneous Bose-Einstein condensate with the repulsive interaction between atoms. It has be...

    Dynamics of vortex structure formation during the evolution of modulation instability of dark solitons

    The nonlinear stage of modulation instability of dark solitons is studied analytically and numerically. We propose an asymptotic description of the dynamics of these solitons in terms of their local velocity a...

    Structure of vortex shedding past potential barriers moving in a Bose-Einstein condensate

    The problem of excitation of a homogeneous Bose-Einstein condensate by axially symmetric potential barriers moving with respect to the condensate with both supersonic and subsonic velocities is considered in t...

    Structural features of solid gallium in microporous glass

    An experimental Debye-Scherrer study of structural features of gallium in porous glass with pore diameter d=4 nm is reported. Gallium structures different from the known bulk modifications have been discovered.
