Stable three-dimensional spatially modulated vortex solitons in Bose-Einstein condensates
V. M. Lashkin
We present exact numerical solutions in the form of spatially localized three-dimensional (3D) nonrotating and rotating (azimuthon) multipole solitons in the Bose-Einstein condensa…
Influence of the mean flow on zonal flow generation
V. M. Lashkin
Excitation of zonal flow by the modulational instability in the presence of mean shear flow is considered. It is shown that the small amplitude mean flow favours the modulational i…
Influence of zonal flows on unstable drift modes in ETG turbulence
V. M. Lashkin, Yu. A. Zaliznyak, A. I. Yakimenko
The linear instability of the electron temperature gradient (ETG) driven modes in the presence of zonal flows is investigated. Random and deterministic - like profiles of the…
Two-dimensional multisolitons and azimuthons in Bose-Einstein condensates with attraction
Volodymyr M. Lashkin
We present spatially localized nonrotating and rotating (azimuthon) multisolitons in the two-dimensional (2D) ("pancake-shaped configuration") Bose-Einstein condensate (BEC) with a…
Two-dimensional ring-like vortex and multisoliton nonlinear structures at the upper-hybrid resonance
V. M. Lashkin
Two-dimensional (2D) equations describing the nonlinear interaction between upper-hybrid and dispersive magnetosonic waves are presented. Nonlocal nonlinearity in the equations res…
-soliton solutions and perturbation theory for the derivative nonlinear Scrödinger equation with nonvanishing boundary conditions
V. M. Lashkin
We present a simple approach for finding -soliton solution and the corresponding Jost solutions of the derivative nonlinear Scrödinger equation with nonvanishing boundary condit…
